Does RDS for MySQL Support Version Upgrades?

  • Upgrading a major version using DRS

    You can use Data Replication Service (DRS) to migrate databases from RDS for MySQL 5.6 to RDS for MySQL 5.7 smoothly. Before using DRS to upgrade a major version, you need to prepare a DB instance of the target version.

    On the Instances page, click the target DB instance. On the displayed Basic Information page, click Migrate Database in the upper right corner of the page.

    For more information, see Creating a Migration Task in the Data Replication Service User Guide.

    Version upgrade
    • DRS only supports migration from an earlier version to a later version. After the migration, you are advised to run the optimize table command on the new instance to optimize the tablespace.
    • If you change the instance class during DRS migration, the instance will be intermittently disconnected twice. After the change is complete, check the DRS task.
  • Minor version upgrades

    RDS for MySQL supports automatic and manual minor version upgrades, which can improve performance, add new functions, and fix bugs.

    For primary/standby DB instances, the standby DB instance is upgraded first and then the primary DB instance is upgraded.

    For more information upgrade operations, see Upgrading a Minor Version.
