current configuration on-premise is 3 Exchange servers:
Exchange 2010 SP3 latest RU CAS,HUB server
Exchange 2010 SP3 latest RU Mailbox server
Exchange 2013 CU 14 Mailbox,CAS
95% mailboxes are in O365
I need to upgrade to single Exchange 2016 in this hybrid environment and decomission Exchange 2010 and 2013 servers.
Is it common migration + rerun HCW at the end of migration?
e.g. I have found this article
which says that /prepareschema is little bit different.Is there any other suprises?
Exchange Deployment assistant does not have option to choose hybrid server migration.
Any advice?Is there any official tutorial for this kind of migration?
