Hi Aref,

it is currently not possible to move your EC2 instance to another subnet (or Availability Zone or VPC). Instead, you can create a new Amazon Machine Image (AMI) from the source instance to manually migrate the instance. You can find a detailed guide here: https://repost.aws/knowledge-center/move-ec2-instance

    Correct. Think about it - the EC2 is provisioned with a private IP which is kept for the lift of the EC2. This IP is allocated according to the subnet into which the EC2 is provisioned. It's not possible to have another subnet with the same range in the same VPC.

    Also the EBS volume which the EC2 uses to boot will be provisioned in a specific AZ, so even if the EC2 instance were able to be moved to another AZ it would no longer be able to attach its root disk.
