Can you make an existing Google domain a subdomain of another?

We have 2 existing seperate Google domains for 2 of our Schools. Is it possible to make one of them a subdomain of the other without losing any data or user accounts?

If you have two Google Workspace setups and you want to merge them into one there is no native way to do this. Its rather manual or you pay a third party to do this. Basic way I've done it:

Add a suitable subdomain on the the one you are keeping.

Recreate the accounts of the incoming domain on the one you are keeping on its new sub-domain - with appropriate polices, OU structure and so on

Recreate Shared Drives on the one you are keeping. Add an account to the shared drives on the doamin you are not keep from the one you are keeping as an owner. You can then simply move the files from old to new shared drive.

If its quite small you can give users instructions on how to use Google Takeout to make a copy of all of their stuff and target their new account - so that does Mail and Drive. You can use the built in migration tool to do Mail in bulk. Or use a third party migration tool if its bigger - used Systool Migrator when I did an incoming secondary.

 

Its not pleasant and it not easy - but it is doable with some effort.

Thanks @rogerdnixon I was hoping it would have been easier. You would think Google would make it easy given how many schools are joining Academies. We will have 5 Google Workspace domains that will need joining at some point!

You might want to just make them Trusted Domains and keep them separate. Also be aware that unless you ate on Plus licencing - each separate domain gets 100Tb storage - combine them you just get 100Tb.
