I'm looking at a cutover migration for a relatively small network (< 50 users). I've seen a relatively good guide here
, however I seem to remember that there's a lot of preparation tasks that need to take place before you can actually perform mailbox migrations themselves.
For example, I understand that you have to make adjustments to AD so that it's a routeable domain (not .local) and adjust UPN names. Is there a definitive list of preparation tasks which apply to cutover, staged and hybrid deployments?
