What is the best way to migrate a single account in commercial and linked account in GovCloud to AWS Organizations

0

We currently have a single AWS account on commercial cloud (Account A) which contains all IAM users, policies, workloads, etc. for our integration tier. This account is tied to a separate account on GovCloud (Account B), which contains all IAM users, workloads, etc. for our production tier. Account A has also purchased many reserved instances that we do not want to lose.


Given this scenario, what is the recommended way to migrate to AWS Organizations in both commercial cloud and GovCloud, while keeping our reserved instances?

We were thinking of doing the following, but aren't sure if there are any gotchas to be aware of:

Part 1: Migrate the commercial cloud account

  1. Create a brand new AWS account that will only be used for management.
  2. In the new account, stand up AWS Organizations.
  3. Invite Account A into the organization, and place them under a Workloads OU.

Part 2: Migrate the GovCloud account

  1. From Account A, create a new GovCloud Account, which will only be used for management.
  2. In the new GovCloud account, stand up AWS Organizations.
  3. Invite Account B into the organization, and place them under a Workloads OU.

That sounds the most logical way to do it and we recommend this for our clients (I don’t work for aws) when transitioning to an org.

Bear in mind you can’t share these reservation’s to other accounts unless purchased in the management account. What I would do is what you have planned and when they come up for renewal, purchase them im the management account when using consolidated billing so they can be shared across your org.

Hope that helps.
