Office 365 coexistence migration
Posted on 2013-06-16
For the scenario planned 20 users from a newly acquired company will be provisioned with say @company1.onmicrosoft.com addresses on our new 365 tenant. if we then, once ready link our on premise to 365 to do a coexistence migration will these users created remain if we use dirsync and adfs or will this delete all existing accounts on the tenant and replace with the dirsync users?
If it doesn't delete is it then also easy to relink them to on premise new AD accounts or do they stay as kind of orphan accounts?
