Instance migration across zones

Last Updated: May 26, 2017

If the zone of an instance is fully loaded or in other cases where the instance performance is affected, you can migrate the instance to another zone.

Note: Currently, only MySQL 5.6 and SQL Server 2008 R2 instances support instance migration across zones.

Background information

  • There will be 30 seconds of transient disconnection during migration across zones. Ensure that your application has a reconnection mechanism.

  • Migration across zones is possible only when the region of an instance has multiple zones.

Operation procedure

  1. Log on to the RDS Console and select the target instance.

  2. Select Basic Information in the menu.

  3. Click Migration zone in Basic Information, as shown in the figure below.
