  1. Hi Renjith

    Good article. I am thinking AD Connect needs to be up and running in terms of service for synnch to work. Therefore, we have two AD connect servers. I guess we follow a sequence. Upgrade secondary and then run the wizard and make secondary the primary and then upgrade what was the primary.


    1. Hi James,

      Sequencing is absolutely fine. However don’t forget to change the staging modes on secondary server while doing upgrade on the primary server and vise versa.
