I recently installed Exchange 2016 and migrated all users from Exchange 2010 to 2016.
I plan to uninstall Exchange 2010 and remove it from domain before decommissioning the Exchange 2010 server.
But I noticed in EAC that the Exchange 2010 has the server roles: 'Maibox', Client Access' and 'Hub Transport' wheres Exchange 2016 only has the 'Mailbox' role.
I already tested by shutting down the Exchange 2010 server and everything including send/receive works fine on Exchange 2016.
So do I need to do anything before getting rid of the Exchange 2010 server?
