Microsoft 365 Minimal or Cutoff Migration?
Hello, I am currently running an on-premises Server 2016 domain with Active Directory and Exchange 2016 with around 65 users. I am starting to plan for migrating our Exchange server to Microsoft...
- You can re-enable sync after the migration, that's not a problem. Do note that if you plan to decommission Exchange, having AAD Connect in the mix puts you in an unsupported configuration. Every configuration involving dirsync/AAD Connect requires you to keep at least one Exchange box for management purposes.
That's the only supported configuration. It's a pain yes, but using the Exchange management tools is the only supported way to manage Exchange related objects and attributes. If you don't care about the "supported" bit, it's perfectly possible to do it with AD tools/PowerShell.
Thank you for the clarification. I think for now I will start with the 'Minimal' option and see how easy things are to manage with Exchange still being in the mix and decide later whether to fully decommission it or not.
