How can we change aws instances region from US East (N. Virginia) us-east-1 to Asia Pacific (Mumbai) ap-south-1?

Question

I deployed all my app on an Amazon EC2 instance in US East (N.Virginia). Now I want to move it to Asia Pacific (Mumbai) ap-south-1 region.

I don't want to change my IP (which one I got from US East (N.Virginia)). And I don't want to lose any activity from the EC2 Instance.

Even I tried Move an EC2 Instance to Another Subnet, Availability Zone, or VPC, but did not get anything.

How can we change this?

Answer 1

1. Take the AMI of the existing machine.
2. Copy the AMI to the new region.
3. Launch new machine from the AMI.

NOTE: You can't keep the existing public IP because AWS has different set of IP's for different regions. To overcome this create a public domain in Route53 and create a A record and change the value of A record to new public IP, use your DNS name instead of public IP everywhere.
