You need all non-volatile TDB files from PDC.
That is, everything from /var/lib/samba/ (or the respective place for your
installation) plus your smb.conf. Do NOT copy files from /var/run or /run or
any other volatile storage. Make sure Samba daemons are properly shut down
before transferring files. Make sure Samba daemons have no way to restart or
otherwise access the old files, when you perform migration. Best to rename
them all away. Just in case. One more backup never hurts.
