All mailboxes and Public Folders are in Exchange Online and I am maintaining Exchange 2010 on premise in Hybrid mode.
What is the correct procedure to introduce an Exchange Server 2016/2019 to replace my old Exchange server in the above circumstances?
From what I have read, I would have to move to Exchange 2016 initially as this is the latest version that will allow co-existence. I think.
If I stage it, is it simply a case of re-running the hybrid wizard to re-establish Hybrid on the new Exchange server?
Would I have to break hybrid mode on the old Exchange server first?
Hi @Chris Yue,
You can do a migration to Exchange 2016 as you describe and after that re-run the HCW using Exchange 2016.
Do I need to take any action against my existing Exchange 2010 server before running the HCW on Exchange Server 2016?
I would suggest you to refer to the below thread..
