I want to make an Amazon Machine Image (AMI) I’ve created available to another AWS account. How do I do that?
If you know the account IDs of the AWS accounts you want to share the AMI with, you can share the AMI by following the instructions at Sharing an AMI with Specific AWS Accounts.
To copy the shared AMI, see Cross-Account AMI Copy.
Note: Sharing an AMI from different Regions is not available. You can copy the AMI and then share it or launch it in a new Region. For more information, see How do I create and copy an Amazon Machine Image (AMI) from one AWS Region to another?
