# 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.
