We created new instances, then started assigning all new clients to the new
instances. Then, we went back and cherry picked the handfull of worse
clients and moved them to the new instances (some by occupance, some by
number
of files). To move them, some we
exported/imported while others we just created new nodes on the new
instance and retired the node on the origional TSM server.

So, did you have multiple tsm instances on the server, each with their own
3584 partition and dedicated drives?

No, you are NOT wrong! (or, is that "yes, you are NOT wrong!")
A library manger is the way to go.

Not very hard. The procedure CAN seem complicated, but when
you work through the steps it's not bad. The only trick
in the procedure is making sure the library manager assigns
the volume ownerships to the clients correctly. This is all
in the procedures.
First, make sure you understand how library sharing works
(see the Admin guide), then the redbook on converting to it.
I spent a fair amount of time working through the examples.
I then wrote a detailed procedure for the conversion
(sorry, I looked for it but can't find it), then got the
outage and performed the conversion. Understand, plan/plan/plan,
ask questions, then do it.
If you can think of a way to test out
a small library sharing environment first, then do it. We were
able to do this since we had new 3584 libraries onsite that were
waiting for library sharing to go in to use them. We used them to setup a
small library sharing environment to play with.

You won't! We had over 6-8thousand tapes in 2 3494 libraries and 2 3584's
with 300-400 tapes. We didn't loose a single tape when we converted!
The library manager environment has it's own issues you will need to
get your arms around. We spent some time balancing the batch schedules
between instances so as to not have one instance hog the drives. It
also becomes fun trying to get a big picture of what all the
instances are doing. I finally wrote a script to give a overall
picture of tape drive usage across the instances, and what
processes/sessions were using them (see below).
Here is the output of my status script . . .
