Change your primary domain for Google Workspace - Google Workspace Admin Help
Set up Gmail by updating the new domain's MX records. The setup won't affect or change your current email. For the steps, go to Set up MX records for Google Workspace. Click I have completed these steps. (Optional) To prevent spoofing (spammers sending messages that appear to be from you), set up SPF and DKIM. Setup takes a few minutes, but really helps your email from being blocked as spam. For the steps, go to Set up SPF and DKIM. Step 3: Switch to new primary domain

r/gsuite on Reddit: Changing Primary Domain on Google Workspace
May 18, 2023 -

Hi guys,

I've found a lot of information online about changing the primary domain of a Google workspace. However, I can't find any information regarding emails with the change of primary domain.

On this Google workspace account, there are active emails where the primary domain will be changed. I understand that domain aliases will be created from the old domain automatically.

Will the emails within the mailboxes be as they were before the primary domain change? Or, with the new domain, does it mean they will have new inboxes?

Thanks!

Changing Google Workspace Primary Domain to one I have as a Secondary Domain
You can change the primary domain without affecting anyone, this only changes what is the primary domain for your account, but users will remain the same. If you want to change the primary email of the users, you have to rename them. Since they already have the email they need as alias, you would need to delete the alias and then rename the users Beware of the impact of renaming a user before you do any changes More on reddit.com

This seems easy to test with little risk.

Maybe rename them if the Drive names include “Atom”? When adding new users in the future, you’ll need to manually select “Honey” since the default will be “Atom”.

Since I'm doing this, I'll provide an answer to help others. I'll update as I go through the process.

Before you start

  • To be safe, I added my personal gmail as a full admin user to every service I use. This is easy to do for a lot of Google services like Analytics and Webmaster Tools.
  • Go to your Google Account page to see where you are using your account for login and other things (https://myaccount.google.com/u/1/permissions). To be safe, switch from OAuth to password login where you can. Changing your primary domain could break OAuth logins.
  • This is a good resource.

Testing

I tested out accounts with multiple domains before doing the switch. I created [email protected] (the current primary domain) and [email protected] (a secondary domain). When I login to Google Analytics (GA) with [email protected], it is a different GA account than the one at [email protected].

For another test, I created a [email protected] account, sent an email, and created a GA account with that email. I then used the G Suite rename feature to rename [email protected] to [email protected]. After renaming, (1) the [email protected] account had the emails from [email protected], and (2) when I logged into GA with [email protected] it had automatically converted the GA account I created before the rename. This is a good sign!

Changing the Primary Domain

I pulled the trigger yesterday, and it worked very well. Almost flawlessly. Here are the steps I took to change my primary domain from old.com to new.com.

  1. new.com was a domain alias of old.com To make it the primary domain, you need to remove it as an alias and add it back as a secondary domain. The only (very small) hitch is that you need to explicitly remove new.com as an alias of all your users and groups. I have just a few users so it wasn't a big deal for me. Mail sent to new.com likely stopped working for a bit, but the rest of the process was so quick that it doesn't really matter.
  2. Now, I held my breath and clicked the button to switch my primary domain to new.com. old.com became a secondary domain. This happened instantaneously.
  3. I logged in to Analytics under old.com and it still worked.
  4. I "renamed" (that's what Google calls it) users from old.com to new.com. This basically switches the accounts from one domain to the other.
  5. I then logged in to Analytics, Webmaster Tools, Google Cloud Console, and Blogger under new.com and they all worked and carried over all the info from the old.com account. This was my biggest concern so I was very pleased that this just worked!
  6. The last step is to change old.com from a secondary domain to a domain alias of new.com. This was the one flaw of the process. The groups for abuse@ and postmaster@ are stuck with old.com and I am not able to move them to new.com. Because of this, I cannot remove old.com as a secondary domain. I contacted G Suite support and they were quite helpful, and I hope to hear back from them soon.

Overall, a remarkably easy process for a fairly big change. Kudos to Google for making this so easy.
