I currently have a deployment scenario where Portal and two web adaptors (portal and server) are all installed on a single machine. The server is running Windows Server 2008 and I would like to migrate Portal and the web adaptors to a new machine running a higher version of Windows.
I've read Esri's documentation regarding migrating to new machines, but I can't find much about migrating web adaptors. My preferred method is to go the HA route and create a second Portal and join the two, then unregister the old Portal on 2008.
But how would I migrate the web adaptors to a new machine? Is it as simple as just un-installing on the old machine, and re-install on the new machine? Or is it going to be more complicated then that?
