HelloFloyds_on_Greenwood
Well if you allow me to summarize
Verify domains in Azure or O365 , keep in mind it MAY take 24 hours to move from one Tenant to another , plan before hands and add extra waiting time just in case
Check external guest identities that they don't make duplicates with actual AD users
Add UPN Suffixes to your Domain/Forest
Install/Upgrade AD Connect , provision users on new Tenant
Add Authoritative Domains run Hybrid Wizard and check all domains , select centralized mail transport if you keep your MX onpremise
In the meantime export all PSTs and plan for the Import procedure with AzCopy
Let me know your thoughts !
