Best 5 Database Migration Tools in 2026: Compare the Top Options

Introduction

AWS Database Migration Service is the strongest overall choice among database migration tools for moving data between different database environments. This roundup covers both managed cloud migration services and tools for tracking and managing schema changes across environments.

Quick comparison

The first three tools move databases to a specific cloud provider. Flyway and Liquibase help manage database changes across environments. Pricing and compatibility depend on your source, destination, and migration setup.

1. AWS Database Migration Service

Best for: Moving data across a wide range of database types and environments.

AWS Database Migration Service is a managed service for migrating relational databases, data warehouses, NoSQL databases, and other data stores. You can use it to move data to AWS or between cloud and on-premises environments.

Its broad source and destination coverage makes it a useful starting point for migrations involving mixed systems. Before you commit, check that your specific source and target are supported, and leave time to configure the service. Compatibility and setup vary by database and migration path.

2. Google Cloud Database Migration Service

Best for: Migrating databases to Google Cloud.

Google Cloud Database Migration Service moves databases to Google Cloud services such as Cloud SQL and AlloyDB. It can copy the initial data, then replicate ongoing changes from the source.

That replication can keep the destination current while you prepare to switch over, which may help reduce downtime. The service makes the most sense when Google Cloud is your destination. It is not a general-purpose tool for moving data to any cloud provider. Check that your source, target, and planned migration are supported before choosing it.

3. Oracle Cloud Infrastructure Database Migration

Best for: Moving databases to Oracle Cloud.

Oracle Cloud Infrastructure Database Migration is a managed service for moving databases from source systems to Oracle Cloud databases. Its support for real-time migration at scale makes it worth considering for large or time-sensitive moves.

Real-time migration can be useful when you need to keep data current during the transition. The service is designed for Oracle Cloud as the destination, so it may not suit a migration to another provider. Check that your source and target match OCI’s supported setup, then make sure the migration plan meets your operational needs.

4. Flyway

Best for: Versioning and applying schema changes across environments.

Flyway uses versioned migration scripts to track database schema changes and apply them in sequence. It works across platforms and offers CLI and API workflows, making it a practical option for teams that want to manage changes as part of their development process.

The versioned scripts are especially useful: teams can review how a schema changed over time and apply updates consistently across environments. Flyway manages database changes, but it is not a general-purpose service for transferring an entire database between clouds. Choose it for controlled schema changes, not bulk data movement.

5. Liquibase

Best for: Managing schema changes with different definition formats.

Liquibase tracks, manages, and applies database changes. Teams can define migrations in SQL, XML, YAML, or JSON, which gives them flexibility in how they work.

That format choice is Liquibase’s main distinction. Teams can use a familiar style while keeping schema changes organized and repeatable across environments. Like Flyway, Liquibase focuses on managing database changes rather than moving entire databases between cloud providers. It is a better fit for ongoing schema updates than for a one-time cloud migration.

How we picked these tools

This list covers two related but distinct tasks: moving database data and managing schema changes over time. We compared each tool’s stated migration scope, deployment model, and workflow. That includes managed services tied to specific cloud destinations and platform-independent tools for managing changes.

No single tool suits every database, infrastructure setup, or migration plan. Supported source and target combinations vary, and product capabilities can change. Before choosing, check the current service details for your database versions, destination, and migration approach.

Frequently asked questions

What is the difference between database and schema migration tools?

Database migration services move data between systems, often as part of a cloud transition. Schema migration tools track and apply structural changes, such as updates to tables or columns, across environments.

When does ongoing replication help?

Replication can keep a destination updated after the initial data copy, reducing how much data needs to move during cutover. Whether it is available and appropriate depends on the service and source-target combination.

What should I check before migrating?

Confirm source and target compatibility, test the migration plan, and decide how you will validate the destination and roll back if needed. Versioned scripts track schema changes over time, and tools such as Liquibase support multiple definition formats.

The verdict

AWS Database Migration Service is the strongest overall choice because it supports a broad range of database types and migration environments. It is a practical starting point for moves between cloud and on-premises systems, though the source and destination determine whether it fits. For migrations to Google Cloud, consider Google Cloud Database Migration Service. For versioning schema changes, Flyway is a strong alternative.
