Explanation

It's not possible to move an existing instance to another subnet, Availability Zone, or VPC. Instead, you can manually migrate the instance by creating a new Amazon Machine Image (AMI) from the source instance. Then, launch a new instance using the new AMI in the desired subnet, Availability Zone, or VPC. Finally, you can reassign any Elastic IP addresses from the source instance to the new instance. https://aws.amazon.com/premiumsupport/knowledge-center/move-ec2-instance/
