Hello! I was wondering if there is some way to download and install feature updates manually. I have about 20 classified offline servers that need to be patched, none of which can connect to the internet. I have an offline WSUS set up, but because it is offline, I need to manually get KBs and import them to the machine to push out. The feature updates, for some idiotic reason aren't on the update catalog so I can't just go grab them. I have a few systems on v 1407. The rest are on 1903.
Would it be easier to remake the 1407 with an up to date version using an ISO? Could that work? Also, is it possible to jump from 1407 to 21H0 in one shot?
For the 1903 servers, same question.
Is the only option to use the media creation tool with a 21H0 install and run that or should I download a 21H0 ISO and do it in place? Can both update the version without affecting files folders and settings?
Thanks for all your help!
