For our last upgrade to 5.4 we ran expiration on the "test" upgrade and a few 
backups and restores without giving access to the real data.  Once upgraded we 
ran a backup, restore with fresh data and a restore with "upgraded" data.

Our last upgrade we ran into a problem during reclaim (fixed with a patch), but 
we have not figured out a way to test that without endangering the data.

Subject: [ADSM-L] TSM upgrade to 5.5.1

Hi,

currently we have TSM 5.3.4.2 running on AIX 5.3 (and an IBM 3494 tape
library with eight 3592 drives, Atape 10.7.3.0) and are planning to
upgrade to 5.5.1.0 soon. I've already tested this upgrade on my test
machine, and it worked fine. This absence of any problem made me even a
bit suspicious. :-)

My questions:

- Which kind of tests would you recommend performing before you'd
declare a new TSM version 'ready for production'? I've read Technote
1196013 and the relevant section in ADSM.QuickFacts. Performing a simple
backup and restore from different clients worked fine, LAN-free is not used.

- Do you know of any pitfalls in 5.5.1.0 or should it be safe to use on
the server?

Regards,
