The AWS generated key can be transferred to another region:
- Log into the instance that was created with the key that you want to transfer.
- Install ec2-api-tools if not already present (sudo apt-get install ec2-api-tools)
Use this command
ec2-import-keypair keypair-name --public-key-file ~/.ssh/authorized_keys --region aws-region
With above steps, I transferred the AWS created key from Singapore region to Oregon region and same key worked perfectly fine for me.
