Christian Stück received kudos from NateS in Migrate ESMC from Windows Server to ESMC VA
Hmm, i would think if you do "clean install with same ip" it should work.
Of course thats more a manual move than a migration because you have to reconfigure everything like polices etc.
Did this once for a customer who wanted to move from VA to Windows and ist was less effort than i thougth.
By my experience its easier to keep all clients when you choose "same ip, same certs".
