That's what I figured.

5.3.6 is the last TSM client version that states it supports W2K. 
5.4.3 is the last TSM client version that states it supports AIX 5.2 

Thanks.

If you're only using the baclient (normal tsm backup client) there is
practically no limit on version intermixing. I've hade customers running
3.x clients against 5.4 servers so 5.x against a 5.5 shouldnt be be a
problem but YMMV.

On Windows you _might_ get problems with systemstate on wildly different
TSM versions but running TSM 5.3 client on Win2k (last supported
version) works without a hitch against 5.5 server, even so for the
5.2/5.3 baclient on AIX.

My rule of thumb is, try it, it will most probably work!

Ofcourse this is is not supported but neither is win2k :)
