Scanner does merge the information *on that volume* with the running
database.  The problem is that if you have more than a small number of
tapes, the time to perform the scan becomes huge.

You can't scan a bootstrap or media backup and merge the information
in the bootstrap.  It's only merging information about that one volume.

Make a list from the old server while it exists (or start up a temp
instance and load it with the old bootstrap).  Then manually find the
tapes you need.  Scan those tapes into the new server.
