If you want to move EC2 instance between regions - built-in AWS tools can help you to do it quite simple. Basically what you need is create image, move it to new region and launch it. In this example we will move instance from US (N. Virginia) to EU (Frankfurt). Below I describe required steps to do it.
Steps to move EC2 instance
Make sure your new instance has the same configuration as previous. Also double check VPC setting, security groups. After launching new instance it will have new IP address. So don’t forget to update domain records referencing to that instance.
That’s it. You have the same instance running in new region.
