we would like to add a third primary Server to our Zenworks Zone.
The Zone consists of two non-Appliance Servers with Zenworks 2017 Update 2.
The downloadable Appliance is ZENworks2017a_Appliance-x86_64.ova so there is no Update 2 included.
Is it necessary to Update the Appliance to Update 2 before adding it to the Zone?
Or can we just add it without any updates installed and install them after that?

Best Regards
Marco Hald
