I've a Windows EC2 instance running in one region and need to move it to another region (Tokyo and Singapore in this case).
Is that even possible? What potential problems do I need to watch out for? (I found https://stackoverflow.com/questions/2181849/ec2-instance-cloning which is describing how to do it, but appears to assume Linux instances, and to assume the same data centre. Is it possible to move my keys across to another region?)
I tried something similar with a Windows instance a few months ago, just trying to clone it in the same data centre, but I couldn't get it working quickly, so I had to give up and just create a fresh instance at that time. This time I've got a bit of breathing space, and want to research how to do it properly!
Root Device Type: ebs
Block Devices: sda1 xvdf
(both are ebs, "attached", and have Delete on termination set to "no"; sda1 is the root device)
The AMI is described as "Unavailable" (then an ami number).

have you tried this very recent feature: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-copy-snapshot.html?ref_=pe_2170_27415460
I think it does just what you need. I tried to upload an image, but my reputation isn't high enough yet.
