Exchange 2010 to Office 365 Migration - Cutover Migration with Dirsync
Posted on 2014-09-30
I'm performing Mail Migration to Office 365 from Exchange 2010(On SBS 2011). While performing the preparations, I installed DirSync and Configured it(without the "hybrid deployment " checkbox); Then I decided to perform "Cutover migration" ,when I found out that Hybrid deployments require an on-premises Exchange server.
Problem / Question: I need to remove On-premises exchange after the migration but I cannot perform a cutover migration with dirsync configured. I tried to deactivate Dirsync and create a batch with an endpoint but, of course, it fails telling me that and object already exists in target forest.
Is there a way to remove, Dirsync, then remove all users, groups, etc from Office 365, then run a cutover migration, then install Dirsync? Or Is there anything else I can do to revert what I have done?
What I would like to do is:
-move all mailboxes to office 365
-configure Dirsync for Password syncronization
