I have hybrid setup of Exchange 2010 with Office 365 and all users have been migrated to Office 365. I have read the recommendation that must have Exchange server on-premises for management task. To take this precaution I would like to update my Exchange 2010 to Exchange 2016. My concern is after installing Exchange 2016 and create coexistence between both servers, do I need to run the hybrid wizard again on Exchange 2016 and then after that decommission my Exchange 2010 server. Please guide.
