While it 'might' be possible, i would not try to ram that square peg into a round hole. Your best course of action is to backup and restore. Honestly, it won't take that long and you aren't going to fall on any sharp edges in the process and lose all of your data. Worked fine back in the Solaris days before we had ZFS. tar, cpio, dump/restore, choose your path, verify the backup and you are good. If you just backup your user data, a clean build will get rid of a lot of cruft at the same time (not to mention fragmentation if you are using spinning rust).
