Hi Geoffrey, Have read your notes on ADSM Server 3.1.2.55 upgrade to TSM 4.1.2. The notes is great. I am also planning for upgrade 2 ADSM servers (3.1.2.13 to 4.1.2 & 3.1.2.57 to 4.1.2). However, there are two very old HP10.01 boxes which runs v2.1 client and a number of AIX4.1 & HP10.20 boxes which run v3.1 client and ADSMConnectAgent, As v3.7 client nor TDP for Oracle are not supporting these old boxes, just want to know if you have any v2.1, v3.1 clients backup to new TSM Server. Any problem so far? Thanks in advance. Regards, Eric Tang
