I switched from VMWare to Proxmox a few years ago because Proxmox supported a wider range of network cards that were more common in the cheap desktop computers I use in my homelab, whilst VMWare almost required an Intel network card (which was usually fine for server hardware).

It was a surprisingly easy transition that I have not regretted one bit. I'm not sure whether there that was an actual migration path, without reinstalling servers from scratch. Homelab meant it didn't quite have the requirements of a production system...
