How do I move an Amazon micro instance to a small instance?

I want to move my instance to a micro instance to a small instance but when I try to launch a new AMI based on my Micro instance AMI it only gives me the option for 64 bit instanc开发者_如何转开发es.

My initial ami is based off an ubuntu 10.04 image.

Is it not possible to move between 64 bit and 32 bit instance?


A 64-bit image requires a 64-bit instance. 32-bit for 32-bit. You can have a 64-bit Micro instance, but I believe that Small instances are only available in the 32-bit flavor.

  • Update: AWS has meanwhile introduced 64-bit Ubiquity, i.e. every instance type can be used with 64-bit images, which indeed will make it easier for you to scale vertically (to larger and smaller instances) without having to maintain parallel (32 and 64-bit) AMIs (see EC2 Updates: New Medium Instance, 64-bit Ubiquity, SSH Client for details).
