How to Split a Single Google Workspace Account Into Multiple Separate Accounts

Let’s say you have:

Account A, with domains A and B

You want to split them up, so you end up with:

Account A with domain A
Account B with domain B

Here’s how:

1. Remove all email addresses at domain B to remove domain B from the account. ​To remove email addresses:
   -Change a user’s primary email
   -Remove a user’s alias
   -Change a Group’s email
   -Remove a Group alias
2. Create a custom new OU for the users you want to migrate
3. Move the users you want to migrate to the new OU
4. Export a list of users in the migration OU
5. Remove domain B.
6. Create a new Google Workspace account, Account B, where domain B is the main domain
7. Migrate data from the users on Account A to the users on Account B:
   1. To migrate emails, use the Data migration service.
   2. To migrate Drive files: have each user manually upload their previously exported files and folders to their new account.
   3. To migrate calendars: have each user manually upload the previously exported events to their new account.
   4. To migrate contacts: have each user manually upload their previously exported contacts to their new account.
8. Delete all users in the migration OU in Account A.
