Can I Change the Region or AZ After an ECS Is Purchased?

Sorry, you cannot change the region after the ECS is purchased. During the ECS purchase, you are advised to select the region nearest to your services for lower network latency and quick resource access.

If you need to change the region or AZ for a purchased ECS, you can use Image Management Service (IMS) to migrate the ECS data across regions or AZs.

Example 1:

ecs01 in a region needs to be migrated to another region.

1. In the original region, create a full-ECS image image01 for ecs01.
2. Replicate image01 from the original region A to the target region and name the new image image01-copy.
3. In the target region, use image01-copy to create an ECS named ecs02.

   In this way, data on ecs01 is migrated from the original region to ecs02 in the target region.

Example 2:

In a region, ecs01 in an AZ needs to be migrated to another AZ.

1. In the original AZ, create full-ECS image image01 from ecs01.
2. In the target AZ, use image image01 to create an ECS named ecs02.

   In this way, data on ECS ecs01 is migrated from the original AZ to the target AZ.
