Will be upgrading TSM server from V4.2.1.15 to V5.1.7.2 in about two weeks. The 
server is on AIX 5.1 ML3.
Two Questions:
 
1.) Is TSM server level 5.1.7.2 reliable?
 
2.) I have two old NetWare clients at the V3.1.0.5 level and two AIX clients at 
the V3.1.0.6 level.  These clients can't be upgraded because of OS levels. Will 
these old clients continue to work after the server upgrade?
 
Thanks in advance for any comments or advice.
