Background of our setup:
We've hosted our web-based application in Amazon EC2 US East (Virginia) Region. Our instance is based on Linux distribution (CentOS) and AMI is S3-backed. 1 EBS volume (400 GB size) is attached to this instance.
We've planned to migrate our deployment to US West (N. California) Region. From AWS doc, I understood that for moving AMI, there is a command-line tool available - ec2-migrate-bundle. But for moving EBS volume across Region, currently there is no tool available.
I'm looking for easiest and/or fastest way of copying/moving EBS volume from one Region to another. Also, are there any hidden risks involved during and/or after the migration?
Experts ideas/suggestions/recommendations on this are highly appreciated.
