ADDS trusted forests.domains A. OnPrem EX2013 B.Office 365 into new ADDS and New 0365 Tenant?
Yes, you are correct. We are going to change UPNs , Primary SMTPs etc and we will decommission Exchange 2013.
Would you recommend something about the process that might help?
Thank you.

Sorry for the late answer , i was quite engaged. So have you started yet ? One this i would like to point out is to carefully plan your Identities , just make clear which one is which and what aliases are on them
What about your PST files ? Are they holding a lots of GB ? In a similar case we uploaded all Data and made the Import Jobs from 365 Admin.

We have not begun.
PST's should be relatively small.
Thanks fro your insight. Much appreciated.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 !
