Hi
We are currently going to merge with another AD company and we have inherited new policies. We currently use (lastname)(initial-firstname).local
ie smithj@domain.com we also use that for email as our primary email.
We are now going to be moving to exchange online and have a new domain name instead of domain.com.au will be using domain.com
With this the new policy also states users emails and logins will change too firstname.lastname.com ie john.smith.com
what is the best approach to change all users UPN name from smithj@local to john.smith.domain.com as their UPN
