GoDaddy wanted to terminate / delete the GoDaddy tenant when I asked them to remove the domain name so to keep that old tenant around for 30 days, I had to manually go through each user in the GoDaddy portal and change the domain name associated to another domain, then go back and delete all the alias emails that that process created, one at a time and only had access to this via the Godaddy portal.SharePoint was by far the biggest pain as all permissions had to be reset manually - nothing I did would carry this over, even third party tools couldn't do it - I expect this was related to the access denied to Connect-MsolService commands.Same goes for OneNote files - these had to be manually exported then imported by the end user.OneDrive data was not able to be migrated using any tool and was left to the end user to migrate manually - Cannot access Connect-MsolService on the GoDaddy side they lock this down.

Mailbox migration was pretty streight forward using the BitTitan MigrationWiz tool - had to manually assign my GoDaddy Office 365 Global Admin user full access to each mailbox to allow impersonation.

So I just finished a painful Godaddy O365 to MS Office 365 T2T migration and it was the most challenging migration to date.
