10 Best Database Migration Tools of 2026

1. 1

   AWS Database Migration Service

   A managed AWS service that copies databases into AWS and keeps them in sync until cutover, using replication instances, serverless capacity or homogeneous migrations.

   9.1overall

   A managed AWS service that copies databases into AWS and keeps them in sync until cutover, using replication instances, serverless capacity or homogeneous migrations.

   Best forTeams moving Oracle, SQL Server, PostgreSQL, MySQL, MariaDB or MongoDB databases into AWS with near-zero downtime.

   Adoption data

   1.5MAWS says customers have used DMS to migrate more than 1.5 million databases.

   Amazon Web Services, AWS Database Migration Service (2026): “Trusted by customers to securely migrate 1.5M+ databases with minimal downtime and zero data loss”

   AWS Database Migration Service is the default way to move a database into AWS while the source keeps running. It handles both homogeneous moves, such as PostgreSQL to Amazon RDS for PostgreSQL, and heterogeneous ones, such as Oracle or SQL Server to an open source engine, with sources that include MySQL, MariaDB and MongoDB. You can run it on replication instances billed by the hour, on DMS Serverless, which scales from 1 to 384 capacity units, or as homogeneous data migrations billed only for the duration of the job. AWS pairs the replication engine with automated assessments and AI-assisted schema conversion that it says reaches up to 90% conversion rates, and with data validation that flags and re-syncs differences. The track record is the strongest here: AWS says customers have moved more than 1.5 million databases with it. The limits are scope and forecasting. It targets AWS, and prices are shown in a regional table rather than as a single headline rate. We compared documented features and published prices and did not run test migrations.

   Strengths

   • +Largest documented track record here, with 1.5M+ databases migrated
   • +Source databases stay fully operational until the migration is complete
   • +On-demand and serverless options have no minimum fees or upfront commitments

   Limitations

   • −Built to move workloads to AWS, so it does not fit a move to another cloud
   • −Hourly rates sit in a regional price table and calculator, which makes quick estimates harder
   • −Fleet Advisor support ended on May 20, 2026

   SummaryPick AWS DMS when the destination is AWS and you need ongoing replication to keep downtime short. Use the pricing calculator on a realistic instance size before you commit.

   Google Cloud Database Migration Service

   A serverless Google Cloud service that migrates MySQL, PostgreSQL, SQL Server and Oracle databases to Cloud SQL and AlloyDB with continuous replication.

   8.9overall

   A serverless Google Cloud service that migrates MySQL, PostgreSQL, SQL Server and Oracle databases to Cloud SQL and AlloyDB with continuous replication.

   Best forTeams moving PostgreSQL or MySQL to Cloud SQL or AlloyDB, or converting Oracle and SQL Server to PostgreSQL.

   Adoption data

   $30.7 billionGoogle does not report Database Migration Service usage separately; Google Cloud revenue rose 103% to $30.7 billion in the third quarter of 2026.

   Alphabet, Alphabet Announces Third Quarter 2026 Results (Form 8-K, Exhibit 99.1) (2026): “Google Cloud delivered record growth as revenues increased 103% to $30.7 billion”

   Google Cloud Database Migration Service is the strongest value pick for teams heading to Google Cloud. Native migrations, such as PostgreSQL to Cloud SQL for PostgreSQL or AlloyDB, or MySQL to Cloud SQL for MySQL, carry no additional charge, which makes it the cheapest managed way to move a Postgres database with minimal downtime. Each job runs serverless, takes an initial snapshot and then replicates changes until you cut over. For heterogeneous moves, a conversion workspace translates Oracle and SQL Server schemas and code toward PostgreSQL, and Gemini assistance, in preview, converts stored procedures, triggers and functions. Those jobs are billed by data processed: change data capture starts at $2.00 per GiB and drops in higher tiers, while backfill is free for the first 500 GiB each month and $0.40 per GiB after that. The drawback is reach. Targets are Cloud SQL and AlloyDB only, so it is not a general tool for moves between other clouds. We compared documented features and published prices rather than running migrations.

   Strengths

   • +Native PostgreSQL and MySQL migrations to Cloud SQL or AlloyDB carry no additional charge
   • +Published per-GiB rates make heterogeneous costs easy to estimate
   • +Built-in conversion workspace cuts manual work on Oracle and SQL Server moves

   Limitations

   • −Destinations are limited to Cloud SQL and AlloyDB
   • −Heterogeneous change data capture at $2.00 per GiB adds up on busy databases
   • −Gemini code conversion is still in preview

   SummaryChoose Google Cloud DMS for PostgreSQL or MySQL moves into Cloud SQL or AlloyDB, where native migrations cost nothing extra. For Oracle or SQL Server sources, price the CDC volume first.

3. 3

   Azure Database Migration Service

   Microsoft's managed service for moving SQL Server, MySQL, PostgreSQL and MongoDB databases to Azure data platforms, online or offline.

   8.8overall

   Microsoft's managed service for moving SQL Server, MySQL, PostgreSQL and MongoDB databases to Azure data platforms, online or offline.

   Best forMicrosoft shops moving SQL Server estates to Azure SQL, Azure SQL Managed Instance or SQL Server on Azure VMs.

   Adoption data

   48%Microsoft does not report Database Migration Service usage separately; it said Azure revenue grew 48% in the quarter ended September 30, 2026.

   Microsoft, Microsoft Fiscal Year 2027 First Quarter Earnings Conference Call (2026): “Azure revenue was ahead of expectations and increased 48%, even with the 3P capacity delays noted earlier, driven by Foundry and improved CPU monetization.”

   Azure Database Migration Service is the natural choice for SQL Server estates moving to Azure. Beyond copying data, it migrates server objects such as user accounts, SQL Agent jobs and SSIS packages in one pass, which covers much of the hidden work in a SQL Server move. Microsoft lists SQL Server, MySQL, PostgreSQL and MongoDB as supported scenarios, with targets that include Azure SQL Managed Instance and SQL Server on Azure VMs. Pricing is unusually friendly: the Standard tier, with 1, 2 or 4 vCores, is free but handles offline migrations only. For online migrations that keep downtime short, the Premium tier is free on 4 vCores for 183 days from service creation and then billed per hour, with a 35% savings plan discount on one or three year terms. PowerShell cmdlets automate batches of databases. The pricing page labels this edition as classic and did not show a Premium hourly figure when we checked, so confirm current rates. We compared documented features and published prices and did not run migrations.

   Strengths

   • +Standard tier is free for offline migrations
   • +Premium 4-vCore instances are free for the first 183 days
   • +Moves SQL Server jobs, logins and SSIS packages, not only data

   Limitations

   • −Online migrations need the Premium tier
   • −The pricing page as fetched did not show a Premium hourly rate
   • −Only useful when the destination is Azure

   SummaryAzure DMS is the cheapest way to move SQL Server into Azure, and the free Premium window covers most projects. Teams leaving Azure or moving between other clouds should look elsewhere.

4. 4

   Fivetran

   A managed data movement platform with log-based, timestamp, trigger and log-free change data capture from operational databases to warehouses and lakes.

   8.2overall

   A managed data movement platform with log-based, timestamp, trigger and log-free change data capture from operational databases to warehouses and lakes.

   Best forData teams replicating Oracle, SQL Server, PostgreSQL or SAP databases into a warehouse or lake on an ongoing basis.

   Adoption data

   $600MFivetran said its merger with dbt Labs would form a company approaching $600 million in annual recurring revenue.

   Fivetran, Fivetran and dbt Labs Unite to Set the Standard for Open Data Infrastructure (2025): “Following close of the transaction, the combined company will be approaching $600M in annual recurring revenue (ARR).”

   Fivetran fits migrations where the goal is a continuously updated copy of an operational database in a warehouse or lake, for example when an analytics stack moves clouds and the source must stay live. Its database replication offers four change data capture methods: log-based reads from the transaction log, timestamp watermarks, triggers that record changes in a side table, and a log-free comparison for small to mid-size data sets. Sources include Oracle, SQL Server, MongoDB, PostgreSQL, Db2 for i, MariaDB, MySQL, SAP ERP and Cosmos DB. Standard plans sync as often as every 15 minutes, and Enterprise adds 1-minute syncs, enterprise database connectors such as Oracle and High-Volume Agent, and a hybrid deployment option. Billing is by monthly active rows with a $5 base charge on each standard connection, and a free plan covers 500,000 MAR. It is not built to cut an application over from one OLTP engine to another, and row-based billing is hard to predict on busy tables. We compared documented features and published prices only.

   Strengths

   • +Four CDC methods cover sources where log access is restricted
   • +Permanent free plan for low volumes
   • +Strong revenue base, approaching $600M ARR with dbt Labs

   Limitations

   • −Designed to feed analytics destinations rather than cut over an application database
   • −Monthly active row billing is hard to forecast for high-churn tables
   • −Oracle and High-Volume Agent connectors are enterprise database connectors on higher plans

   SummaryFivetran is the safest managed choice for replicating production databases into analytics platforms. For an application cutover between engines, a cloud DMS or Qlik Replicate fits better.

5. 5

   Qlik Replicate

   Enterprise replication software that uses log-based, agentless change data capture to copy and sync data across databases, warehouses and Hadoop, on premises and in the cloud.

   8.2overall

   Enterprise replication software that uses log-based, agentless change data capture to copy and sync data across databases, warehouses and Hadoop, on premises and in the cloud.

   Best forLarge enterprises replicating many heterogeneous databases, including mainframe and on-premises systems, with minimal source impact.

   Adoption data

   75%Qlik says 75% of the Fortune 500 are its customers, across its analytics and data integration products.

   Qlik, About Qlik (2026): “75% of Fortune 500 customers”

   Qlik Replicate is the enterprise heavyweight for keeping many different databases in sync during a migration. It reads changes from the transaction log remotely, which Qlik calls agentless or zero-footprint replication, so nothing has to be installed on the source or target and production load stays low. A graphical interface sets up replication across major databases, data warehouses and Hadoop, on premises or in the cloud, without hand-written code. Qlik describes the zero-downtime pattern directly: copy the existing data, then use change data capture to keep the new system in sync until cutover. Its customer examples include a credit services firm that applied 14 million source changes in 30 seconds and an insurer that cut a nightly batch from 6 to 8 hours to under 10 minutes. Qlik says 75% of the Fortune 500 are customers, though that spans all its products. The cost is opacity: there is no public price, and it is more platform than a one-off project needs. We compared documented features and did not run the software.

   Strengths

   • +Agentless capture keeps load on production systems low
   • +Covers on-premises, cloud and Hadoop endpoints in one product
   • +Customer example: 14 million source changes applied in 30 seconds

   Limitations

   • −No published price; licensing goes through sales
   • −Built for enterprise estates, heavy for a single small migration
   • −Adoption figure covers all of Qlik, not Replicate alone

   SummaryQlik Replicate suits enterprises that need one replication engine across many source and target types. Expect a sales-led purchase and plan it as a platform, not a one-time tool.

6. 6

   Airbyte

   An open source data integration platform with CDC connectors for major databases, available free to self-host or as a usage-priced cloud service.

   8.1overall

   An open source data integration platform with CDC connectors for major databases, available free to self-host or as a usage-priced cloud service.

   Best forEngineering teams that want an open source or low-cost way to replicate database tables into another store.

   Adoption data

   25,000Airbyte says more than 25,000 companies use its platform, including one in five Fortune 500 companies.

   Airbyte, Airbyte homepage (2026): “25,000+ Companies 1 in 5 Fortune 500 companies”

   Airbyte is the budget and open source route for moving database tables between systems. Its CDC connectors cover Postgres, MySQL, SQL Server, MongoDB, Oracle DB, SAP HANA and IBM Db2, and each schema gets an initial snapshot before change tracking begins. Airbyte Core is free to self-host under the Elastic License 2.0, while Airbyte Cloud starts at $20 a month for 5 credits, about 1 GB of syncs, with a 14-day trial of 400 credits. Standard syncs as often as every hour, Plus every 15 minutes, and Pro every 5 minutes on capacity pricing. Airbyte says 25,000+ companies use it. The trade-off for migrations is timing: Airbyte's docs say it does not treat CDC sources as infinite streams, so changes arrive per sync rather than continuously, and cutover windows depend on sync frequency. Newly added schemas also need a snapshot before CDC picks them up. We compared documented features and published prices and did not benchmark syncs.

   Strengths

   • +Free self-hosted option with no row limits from the vendor
   • +Low $20 a month entry price on Cloud
   • +Large user base of 25,000+ companies

   Limitations

   • −CDC runs as scheduled syncs, not as a continuous stream
   • −New schemas and columns must be snapshotted before CDC tracks them
   • −Self-hosting Core means you run and maintain it yourself

   SummaryAirbyte is a good fit when cost matters more than second-level freshness. For a live application cutover, pair it with a short freeze or use a streaming CDC tool.

7. 7

   Striim

   A real-time data integration and streaming platform with log-based CDC from Oracle, PostgreSQL and MongoDB, offered as a managed cloud or self-hosted.

   7.9overall

   A real-time data integration and streaming platform with log-based CDC from Oracle, PostgreSQL and MongoDB, offered as a managed cloud or self-hosted.

   Best forTeams that need sub-second replication between databases and clouds, such as zero-downtime Oracle moves.

   Adoption data

   100 billionStriim says its platform processes more than 100 billion events a day with sub-second latency.

   Striim, Striim 5.4.2 Brings NLP and MCP-based Real-Time Data Intelligence for Agentic AI (2026): “to achieve sub-second latency in processing over 100 billion daily events for ML analytics and proactive decision-making”

   Striim is built for migrations that cannot tolerate a long freeze. It streams changes from source databases with log-based CDC, including what Striim describes as industry-leading Oracle, PostgreSQL and MongoDB capture, and says it processes more than 100 billion events a day at sub-second latency. You can run it as Striim Cloud, a fully managed service billed on the data you move, or as Striim Platform on your own infrastructure with clustered high availability. A useful addition for migrations is Validata, which compares full or partial datasets between systems, flags mismatches and generates reconciliation scripts, so you can prove the target matches before cutover. Release 5.4.2 adds an MCP server and real-time delivery to BigQuery, Snowflake, Redshift, ClickHouse, Fabric and Databricks. The free Developer plan covers up to 25 million events a month for testing. Production pricing is only available from sales, which lowers its value score. We compared documented features and did not run pipelines.

   Strengths

   • +Continuous streaming suits short cutover windows
   • +Validata checks that migrated data matches the source
   • +Free Developer plan for testing up to 25 million events a month

   Limitations

   • −Paid plans have no public price
   • −Developer plan is sized for learning and small use cases
   • −Fewer published adoption figures than the cloud providers

   SummaryStriim is the pick for continuous, low-latency replication across clouds when you also want built-in data validation. Budget time for a sales-led quote.

8. 8

   Redgate Flyway

   A schema-as-code migration tool that versions database changes with application code and deploys them through CI/CD to 60+ database engines.

   7.8overall

   A schema-as-code migration tool that versions database changes with application code and deploys them through CI/CD to 60+ database engines.

   Best forDevelopment teams that need versioned, repeatable schema migrations across environments and engines.

   Adoption data

   200,000Redgate says more than 200,000 data professionals, including 92% of the Fortune 100, use its database tools.

   Redgate, About Redgate (2026): “More than 200,000 data professionals across the globe, including 92% of the Fortune 100, rely on Redgate’s solutions to enable automation, resilience and efficiency”

   Flyway solves a different part of a database migration: getting the schema right and keeping it consistent across environments. It treats migrations as versioned SQL scripts stored with application code, then applies them in order through your CI/CD pipeline, with integrations for GitHub Actions, Azure DevOps, GitLab, Jenkins, TeamCity, Octopus Deploy and more. Redgate says Flyway supports 60+ databases, with advanced comparison and script generation for SQL Server, Oracle, PostgreSQL, MySQL, Databricks and Snowflake. Flyway Enterprise adds drift detection, generated undo scripts, policy-as-code checks before merge, an audit trail and an MCP server that routes AI-generated schema changes through the same controls. Flyway Community is free for individuals and education, and Enterprise has a 28-day trial but no public price. Redgate reports 200,000+ users across its tools. The limit is clear: Flyway does not copy rows between engines, so pair it with a replication service for the data. We compared documented features only.

   Strengths

   • +Free Community edition for simple projects
   • +Plain SQL migrations with no proprietary language
   • +Backed by a vendor with 200,000+ users

   Limitations

   • −Moves schema changes, not bulk data between engines
   • −Enterprise pricing is quote-based
   • −Community edition is aimed at individuals and education

   SummaryUse Flyway to version and deploy schema changes during and after a migration. Pair it with a replication tool for the data itself.

9. 9

   pgloader

   An open source command line tool that loads data and schema into PostgreSQL from MySQL, SQLite, MS SQL Server and files in a single command.

   7.3overall

   An open source command line tool that loads data and schema into PostgreSQL from MySQL, SQLite, MS SQL Server and files in a single command.

   Best forEngineers moving a MySQL, SQL Server or SQLite database to PostgreSQL who are comfortable running the job themselves.

   pgloader is the specialist on this list: it does one job, loading another database into PostgreSQL, and it does it from a single command. Point it at a MySQL, MS SQL Server or SQLite source, or at DBF, CSV and fixed-format files, and it translates the catalog into PostgreSQL types using casting rules, then loads the data in parallel. Version 4 is a full rewrite distributed as one self-contained JAR, keeps the same load file syntax and flags as version 3, and accepts plain JDBC connection strings. The tool stays free and open source. Its author sells support tiers, from a best-effort community level to subscriptions with priority queues and SLAs, priced in euros, plus self-serve MySQL and SQL Server to PostgreSQL courses. There is no published adoption figure, so it scores low there. It is also not a managed service, so you provide the compute, handle downtime planning and run the cutover. We compared documented features and did not run test loads.

   Strengths

   • +Free and open source
   • +One command handles schema and data for common sources
   • +Optional paid support and migration courses

   Limitations

   • −Target is PostgreSQL only
   • −Self-run tool, so you manage infrastructure and cutover
   • −Support tiers are priced in EUR

   Summarypgloader is the fastest free route from MySQL, SQL Server or SQLite into PostgreSQL. Choose a managed cloud service instead if you need continuous replication with little hands-on work.

    Bytebase

    A database change management and governance platform for planning, reviewing, approving and deploying schema changes and controlling access.

    7.2overall

    A database change management and governance platform for planning, reviewing, approving and deploying schema changes and controlling access.

    Best forTeams that want review and approval workflows around schema migrations and production database access.

    Bytebase covers the governance side of database migrations. Teams plan, review, approve and deploy schema changes and data fixes through one workflow that replaces ad hoc scripts, and the same platform controls who can query production, with dynamic data masking, just-in-time access and immutable audit logs. A newer MCP server gives AI agents their own identity so their queries and changes pass through the same masking, review and audit as engineers. It runs self-hosted or in the cloud, with Terraform and API support. Pricing is published: the free plan covers up to 20 users and 10 database instances, Pro costs $20 per user per month and adds SSO and groups, and Enterprise has a 14-day trial with yearly billing. Bytebase does not publish a user or customer count, so adoption is scored conservatively. Like Flyway, it does not copy data between engines, so it belongs next to a replication tool in a migration plan. We compared documented features and published prices only.

    Strengths

    • +Free plan covers up to 20 users
    • +Clear per-user price on Pro
    • +Combines change management with access governance

    Limitations

    • −Governs schema changes and access, not bulk data transfer
    • −Free and Pro plans are capped at 10 database instances
    • −No published customer or user count

    SummaryBytebase is a sensible add-on when a migration needs reviewed schema changes and tighter production access. It does not replace a data replication service.
