I need to safely add a secondary domain in my existing Google Suite Legacy (free) edition.
Alternatively it can be done changing the primary domain (impossible as far as I know).
Of course I need to keep the free (legacy) edition of Google Suite without having to upgrade to paid version

Should take less than an hour to set up this extra domain. You are right about the main domain of the account. It cannot be changed.
