Marc, if you can afford little bit more time I would recommend you to test it first to ensure it will run smoothly: 1. Get another box capable to run AIX 4.2.1 (it can be hard those days :-) and put ADSM 3.1 on it. 2. Restore your TSM DB to this "new" box. Just the DB, there is no need to attach to it any storage devices. And do not forget to disable schedules in dsmserv.opt - your test server can try to contact several nodes in prompted mode. 3. Perform OS and TSM upgrade. 4. Backup upgraded DB and restore it on new production server. If all this completes successfully you can be sure real upgrade+migration would be fine. And you will not be in a hurry. There are no two ways to upgrade - I am sure you cannot put AIX 4.2.1 on your brand new server :-) Yes, you can put ADSM 3.1 on AIX 4.3 and then upgrade to TSM but better perform upgrade on the old box and only restore the DB on the new server. If you are not confident in the success of the migration perform the upgrade same way - do 1, 2, 3 and 4. Thus in case of problem/failure you can stay with your old server and try again next day/week/month. If this insurance is still not enough - sign a contract with a consultant :)
Zlatko Krastev IT Consultant Please respond to "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> Sent by: "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] cc: Subject: ADSM 3.1 to 4.2.1 Migration Hello Again, Since we are getting a new library we are also getting new server hardware and going to TSM 4.2.1 (5 will be later). Therefore, we have a 2 way upgrade (old software to new software, old server to new server). I gave TSM support a call and asked what their recommended procedure was and I found out that they really don't have any, but the tech support guy who responded gave me a procedure that he says has worked for others. In our case, we need to upgrade the OS on the old server (still at 4.2.1) to 4.3.3. Do an update install of TSM on top of what we have now. Export the database after it has been transformed by the update/install to tape. Take the export tape and import it into the new server (along with the old tape libraries). Then migrate the data from the old library to the new library. Is this what others have done? I have seen snippets of other things being done, but usually it appears that server hardware remained the same. TIA for all of your comments. Marc =============================== Marc D.
