jbedit is pretty stable these days. Back in the 7.2 era I wouldn't have
trusted it but now it works. The only missing step is to recreate the
tape device in NetWorker, in between your two jbedit commands. jbedit -d
removes the tape drive from NetWorker whether you want to or not.

You can't shut NetWorker down to do this, jbedit requires NetWorker to
be running (fairly obviously). The timing of moving the drive is not too
important, except to have the drive in place before you define it in
NetWorker.

If you want to be paranoid, you could copy your res directory before you
start, to facilitate an easy rollback if it goes t-up. Not that I would
expect it to.
