We are currently running Exchange 2016 in Hybrid environment for management purposes only. So I am very happy to see the announcement about being able to run the management PS tools on a client machine so I can turn off this old exchange server.
My question is: can I just run the 2019 CU12 installer on my Win10 workstation selecting the "management tools" option, presumably let it update the AD schema to EX2019? and then turn off the existing EX2016 server? Or do I have to setup a new Windows server box, install the full exchange server 2019, so it knows about the existing 2016 version and do any migration necessary?? then once its all done, unistall the EX2016 server and finally turn off the new EX2019 server?
Obviously the first option is preferable and its much less work for me!!
