Install on Windows

I have Home Assistant installed and running on a windows 2012 server for about a year or so. I would like to upgrade but there are no versions available that I can install on windows, all installs run as a virtual stand alone or docker install. Is there a way to upgrade or if I install in a docker, how can I use the current configuration?

If you want to dedicate the machine to Home Assistant , you can do the generic x86 install. A move Im very glad I made.

The windows install has challenges, e.g. using windows-docker it cannot run ‘host’ and that will provide issues with connectivity. Suggesting to either go for some lx variant under docker (if you want docker) or follow @Rich37804 proposal.
