Last Updated:Aug 16, 2023

You can follow the general procedure in this topic to create and manage a task in data migration mode.

Background information

  • Use cases

    Typical scenarios include data migration to Alibaba Cloud from an on-premises system, migration between any two cloud providers, and data migration between instances within Alibaba Cloud. For more information, see Use cases.

  • Migration paths

    For more information about supported data sources and targets, see Data migration.

  • Data type conversion

    Different database engines use different sets of data types. You can check the data type conversion that DTS applies between the source and target databases during schema migration. For more information, see Data type mappings between heterogeneous databases.

    For more information about the features of a data migration task, see Data migration mode.

Data migration procedure

You can complete the following higher level steps to create and manage a data migration task.



1. Set up a network environment

Before you use DTS for data migration, you must make your source or target database reachable by DTS servers over the network.

For more information, Set up a network environment for replication

2. Create a data migration task

Create a data migration task in the DTS console. For detailed, step-by-step procedures about specific migration scenarios, see Overview of data migration scenarios.

3. View the progress of a data migration task

View the progress of schema migration, full data migration, or incremental data migration in the DTS console.

For more information, see View the progress of a data migration task.

4. Switch applications to the target database

Switch your applications to the target database. In this step you can also prepare a rollback solution to minimize the disruption caused by any error to your business operations.

For more information, see Switch workloads to the destination database.

5. Stop the data migration task

After data migration and switchover are complete, stop the data migration task if you no longer need the task.

For more information, see Stop a data migration task.
