I am migrating 18 domains from one office365 Tenancy to another.
Let's call them T1 [source] and T2 [destination]. I have migrated smaller domains first to test and have ran into some changes which are fine with only 3-4 users per domain, but when i have 200 user domain migration i will need some automation and good Powershell scripts to help. To date I have gathered a lot of useful scripts, but am not sorely missing the following... Any ideas where or what i can do to get them ?
Remove Vanity domain from any user with it as an alias or Primary domain.#
Bulk Purge all "deleted contacts" or at least bulk delete from CSV.
Assign Vanity domain from CSV, ideally setting as either Primary or Alias.
