This has, I believe, been done, but not by me, so I am unsure just what
you need to backup and more importantly, where you need to the various
backup files. What to backup is fairly easy, Ubuntu uses two locations,
/var/lib/samba and /var/cache/samba, just backup everything in these two
locations that end in .ldb & .tdb using tdbbackup. If you self compile
samba, everything goes into /usr/local/samba and you would need to put
the files you backed up into the required places, if it would help, I
can provide a directory listing for /usr/loca/samba.

Got to be honest here, from what you have posted so far, I get the
feeling your Samba database is badly corrupted and you will have to
start again. It should be possible to upgrade if your database is ok,
but I would do it first on a test machine.
