Either 1 or 2 should work.

Alternatively, if the old fileserver (client) is not being used anymore, you
can probably just change the Client Address= line in the Director's config.
This has the advantage of allowing old tapes to be reloaded into the database
with bscan (since the client's name is written into the job).
