That can be done, but as others mentioned, if you don’t have permissions/other attributes for the files it’s going to be a real PITA to get everything working. If I had to do that I’d just copy over the files, chown everything to root and then use package manager to reinstall everything, but even that will most likely need manual fixes and figuring out what to change and to what value will take quite a bit of time and complexity of it depends heavily on what you had running on the host, specially things under /var.
