Impact on Data Studio after changing a user's email domain within the same Google Workspace account (primary domain change)

Data Studio Data Studio Q&A

Hi all,

We are planning to change the primary domain of our Google Workspace account and would like to understand the impact on Data Studio (no-cost version) before we proceed.

Our situation
  • Current primary domain: old-example.com
  • New primary domain: new-example.com
  • We will add new-example.com as a secondary domain, switch it to primary, and then change each user’s primary email from user@old-example.com to user@new-example.com in the Admin console.
  • This is a rename within the SAME Google Workspace account. We are NOT migrating to a different Workspace account, and we will NOT delete or recreate any user accounts.
  • The old domain (old-example.com) will remain as a secondary domain, and each user’s old address will remain as an email alias.
What we have checked
  • The “Transfer ownership” documentation says that for Google Workspace users, ownership can be transferred to another person in the same organization.
  • We found community threads about migrating to a different Workspace account, and about reports becoming orphaned after an account was deleted and restored, but nothing about renaming a user’s email domain within the same account.
Questions
  1. After the rename, can users sign in to Data Studio with their new address (user@new-example.com) without any additional steps?
  2. Will reports and data sources in “Owned by me” remain owned by the same user after the rename?
  3. If a report is shared with a specific old address (user@old-example.com), will the user still have access after signing in with the new address?
  4. If a report is shared with the domain (old-example.com), will users whose primary address has changed to new-example.com still have access? Do we need to add new-example.com to the sharing settings?
  5. Will data sources that use the owner’s credentials continue to work, or will they need to be reconnected?
  6. Are there any other known issues or recommended steps before or after this kind of domain change?

If anyone has gone through a similar primary domain change, we would really appreciate hearing about your experience.

Thank you!
