Hello there,
the customer situation right now is like:
- Migration from on-prem Exchange2010 (SB2011) to EXO already completed before a few month (included connectors, mail flow in and out public folders and all stuff)
- Azure AD Sync is running and all mailbox users in the cloud are synchronized from the on-prem AD
- SBS2011 is running on a Windows Server 2008 (DC) and there the hybrid-migration just didnt work (even with MS Support)
as it should be after:
I just wanna decommision the on-prem EXC2010 without losing any of the synchronized mailboxes / AD User in the cloud, so I finally can remove the sbs2011 and complete the new DC server (Windows 2019).
SBS2011 would be just shutdown if there is another DC in the network at the same time.
Think that I have to set the azure sync off while I delete the databank, address books, mailboxes in the on-prem exchange before the deinstallation?
Anyone here already did something like that before and can give some tipps or introductions?
Thanks in advance!
