Migration the GMail account

Approach

• I will keep the email addresses as primary emails, using a forwarder dervice by my domain hoster.
• All users will have @gmail.com accounts for everything Google
• I will move all Google Apps data to those accounts whereever possible

I have a Chromebox that I will use to verify that the new accounts are fully working (we are using ChromeOS *a lot*).

I also use a Synology NAS that can keep intermediate backups.

Freeing your account from GSuite for use in GMail

Once all GSuite data has been migrated successfully, you may want to retain the GSuite account, either as a backup or for all the stuff you can't (yet) migrate), but you may also want to use the email address as an alternative address and login in GMail.

I can not yet confirm this works, but you should be able to update the user in https://admin.google.com/ac/users with a different email address, which can then (hopefully) be used for Play Store, Youtube and the like?

Issues without solution:

Account credentials vs. EMail address

• At some point (sooner than later) I may want to switch my MX record to a different email service. Once I do that, will I still be able to log into Google Apps?

Android / ChromeOS

• Removing the Google Apps account from Android / ChromeOS will make you lose all settings as well as apps and subscriptions from Google Play

Hangouts / Google Meet

• Removing the Google Apps account means you will no longer be reachable through your old email address

Google Fit

• How can you transfer health data out of the Google Apps account?
