Yeah, same sentiment. If at all possible, use linux on the enterprise side. Virtually all of the main domain infrastructure can be migrated. Granted, it's actually very painful, especially for those uninitiated.
So there's that.. But once it's done, I imagine life'd be much smoother for a veery long time.
It's immensely painful if you insist on AD and Group Policy management. If you don't mind dropping that in favor of something like Centrify, or you use web-based product suites (like Google Workspaces, Nextcloud, etc), then it's a lot easier to switch.
