I’ve just taken on a new customer who is buying their company out of a larger firm. It all seems to be fairly amicable and friendly. Their domain is currently pointing MX to an Office 365 tenant that belongs to the current parent firm and we need to extract it.
Last time I had to do this MS told me I had to do without the domain for 90 (Ninety, count them) days whilst “the back end caught up” so we just migrated to Google… That was about 5 years ago though.
I assumed there would be a tenant to tenant migration process direct from MS but I dont see one.
I could; check what mailboxes exist (only 3-5), make local PST files, download everything, drop the domain from the current tenant, setup a new tenant, wait 48 hours, add the domain to the new tenant, upload from PST.
Does anyone have any better solutions? I’ve got two GoDaddy O365 to migrations on the cards as well so any help would be appreciated.
