How can an EBS volume that is currently attached to an EC2 instance be migrated from one Availability Zone to another?
Simply create a new volume in the other AZ and specify the original volume as the source.
Create a snapshot of the volume, and create a new volume from the snapshot in the other AZ.
Detach the volume, then use the ec2-migrate-volume command to move it to another AZ.

How can you check the operational validity of your AWS CloudFormation template?
To check the operational validity, you need to attempt to create the stack.
There is no way to check the operational validity of your AWS CloudFormation template.
To check the operational validity, you need a sandbox or test area for AWS CloudFormation stacks.
To check the operational validity, you need to use the aws cloudformation validate-template command.
