How to merge 2 Google Workspace but 2 domain still separate

[alex993]

Hi all,

My company have 3 three domains. 1 domain use O365, 1 domain use GGWS and 1 domain use GGWS other. Now, I want to merge 3 three domains and mail, onedrive, ggdrive, but 3 three domains' stills separate, what can I do?

Assuming you want to give up one GWS account and the O365 account: You would add the other two domains to your primary GWS account and add them as "secondary domains". This will give you three isolated GWS "instances" under the same GWS account.

Note that when I say "isolated" or "separate" it really means that each domain has its own set of users, but everything will still be combined under the same administration umbrella.

Make sure you also read about the limitation when it comes to multiple domains under one account (see second paragraph, "Secondary Domains"):

Also, I should add, this process does not migrate any data. That would be another topic.

Tks for your answer,

After I add 2 domains to secondary domains, how i can migrate data (mail, onedrive, ggdrive)?

[cryptochrome]

I recommend a third party data migration service such as CloudM (https://cloudm.io). Google's own data migration services (there are two) are pretty limited and hard to set up. Something like CloudM is straight forward to use, affordable and allows migrations between different services like O365 > GWS.

I know that this is something that comes up quite often - especially around migrating two separate Google Workspace domains into a single one. I've compiled a wee writeup here about what kind of strategies you could use to do this.
