Exchange 2010 hybrid setup migration to Exchange 2016

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.

Yes, after creating Exchange 2016, you need to rerun HCW to choose Exchange 2016 as the hybrid server. The Exchange Deployment Assistant could help you deploy Exchange 2016 coexist with Exchange 2010.

Thanks for your response.

If I don't want to coexistence of Exchange 2010 to 2016 as all the users have migrated on Office 365 then in that case also run the HCW. Please guide.

The supported way is created coexist then uninstall the Exchange 2010. If you don't want to create coexist, you need to remove local lab, then install Exchange 2016, then sync account back to local AD and re-hybrid.

Personally, the coexist way is more simpler.
