Thanks a lot for your informations, but there is still en question about this upgrade.
On my site, i have 2 servers, one in 3.1 , the other in 4.2. The question is : how do i do to migrate all my clients ADSM on the server 4.2. The two servers are operationnals. If i migrate à client to TSM4.2, how do i do to restaure or retreive data which have been saved in ADSM 3.1?

Your documentation will describe an "upgrade installation", including such important matters as ensuring you have copies of the volume usage and primary storage pool definitions files. I would very strongly suggest that you download the latest "patch" or "maintenance" release of the TSM server and client software before you begin! With some servers and clients you will find that the fully- qualified path name to the server and/or client software will have changed. Please note that and make any required changes in your dsm.opt and/or dsm.sys files. Also, when you upgrade your environment, please ensure the TSM server(s) are the first systems you do. That is because the 4.2 server will back up all previous releases of the client, including ADSM 3.1, but an ADSM 3.1 server is not guaranteed to back up a TSM 4.2 client. If you are using certain tape libraries/drives, such as the IBM 3494 library with the IBM 3590 drives, please ensure you have the latest microcode installed to those devices. Otherwise, your backups will almost certainly fail as soon as the new server software is installed. If I understand your question properly, I think you are asking if there are any special steps, such as "export" and "import" of backup data as part of the migration. That is not at all a necessary step! Simply upgrade your server, and then upgrade your clients, and the process is complete. Good luck! Dennis Glover
