Yep, pretty much that simple.

Check the tapes out of one library, check them into another.
No more complicated than if you are going to a DR site that has a 3584 rather 
than a 3494.
TSM doesn't care.

There are some differences in the library management:

If you are talking to the 3494 library interface via TCP/IP now, that changes.  
(Some people use the TCP/IP interface, some use a serial cable.)
TSM talks to the 3584 library via the atape drive over the fibre, it has its 
own device number/path.

Thomas already mentioned that the 3584 can be partitioned into logical 
libraries.
If you have multiple TSM servers or other apps using the 3494, you keep them 
separated now by 3494 category codes, those go away.  
You have the logical libraries now instead.  Carts get assigned to the logical 
libraries based on a volser range filter in the library interface.

Subject: [ADSM-L] Tape library possible replacement - push/pull

We are starting to examine the idea of replacing our aging 3494 (installed
1995) due to difficulty in getting parts and having more frequent outages due 
to robot issues.

Since we have 17-TS1130 drives, the natural transition would be to a 
TS3500/3584.

If we go down this route, one issue might be the floorspace/placement,  which 
might require a weekend eject-push-pull-reload.

Never having dealt with any tape library other than the 3494, I am trying to 
collect as much info as I can on doing a swap-out.

Is it as simple as defining the new library, moving the drives/paths to it,  
changing the devclass to point to the new library, checkin everything 
(scratch/private)??  Am I missing anything?
