EBS Volume Migration
  • EBS Volumes - Availability Zone
    • Amazon EBS volume is tied to its Availability Zone.
    • It can only be attached to instances in the same Availability Zone.
  • EBS Snapshot - Regional
    • An EBS snapshot is tied to its region.
    • It can only be used to create volumes in the same region and has to be copied from one region to another if needed.
  • So, to migrate an EBS volume from one AZ to another: 1. Create a snapshot of the volume. 2. Restore another EBS volume from that snapshot but in another availability zone.
