I think that you'd have a lot of problems with moving it to Virtualmin server since Virtualmine has "a mind of his own"

Maybe if you manage to "repair" all the links like site's home folder, and all other links then the site might even work.....

But I believe other more experienced members here on una.io can give you more comprehensive answer. I am running una site out of Virtualmin althoug I have it also running on my server......

Best regards
