Exchange Online - Tenant to Tenant migration disable AD Connect

Hi all,

 

We are in the middle of a tenant to tenant migration for Exchange Online.


We have users using different domainnames so i did a little testrun with a few people who use a certain domainname.

 

Current situation is:

Local AD, synced with O365 via Azure AD Connect.

 

When migrating the small group of people, I opened the Azure AD settings and disabled syncing these users by disabling syncing their OU.

What then happend was that all users got deleted in O365.

 

It took me a while to restore them and what I did does not seem to be the best approach.

 

How do I make the remaining users 'Cloud users' without changing the Azure AD connect settings?

When i searched online i found this powershell command:

Set-MsolDirSyncEnabled -EnableDirSync $false

 

Will this be enough?

Or does anyone has another best approach :)?

 

Thanks.

    That's the only supported method. An unsupported and a bit scary alternative is to delete the user in O365, then simply recover it from the recycle bin. This effectively makes it a "disconnector" and you can manage it directly in the cloud.

      VasilMichev Thanks for your reply!

       

      By only supported method, do you mean the first part (edit AAD Connect) or the second part (disabling the sync by running this ps-cmd; Set-MsolDirSyncEnabled -EnableDirSync $false).

       

      Thanks again!
