Depending on the network connection it is much faster to export the data and import it in one step. You don't use virtual volumes just he server to server communications. Before this all in one step using server to server was slower. Now I believe it is faster.
We have migrated many nodes from one server to another as we have expanded over the years. We have found that it very easy to export nodes who have 100 - 500 GB of data in TSM. For nodes over 500 GB you may still be able to export if you have 1 Gb NIC's. If not then you may need to cut over the large servers with new full backups. We just got done migrating 800 or so nodes from 4 older Intel servers 3 new Intel Servers. The purpose wasn't just to upgrade the hardware because we could have DR'd onto the new systems for that. We were moving from an all Tape solution to a solution where all files under 3GB would stay on ATA disk. As Wanda stated though if both systems need to use the same library at the same time then you will need to set up library sharing. In our case we use STK 9310 silo's and Gresham's EDT software so all our systems can easily share the libraries. "Prather, Wanda" <[EMAIL PROTECTED]> wrote: Yes, I have done it. There is no direct or easy way to move a TSM system from one platform to another. The data and the TSM data base are not in a compatible format between Windows & AIX. If it is practical for you, the simple solution is to start clients backing up to the new Windows server, and just keep the old AIX server around until the data expires. For that to work you would need a new tape library, or need to SHARE your tape library between the two TSM servers for a while. If you want to move the data to the new Windows TSM server and you have compatible media (same type of drives in the tape library), you can EXPORT the data from the old server, and IMPORT it into the new server. For this to work, you should be sure that the new AIX TSM server is at the same level (5.1.6) as your old server. This is obviously takes a lot of time for you. If you don't have compatible media, you can set up server-to-server communications (if you have the DRM license, or TSM Extended Edition) and send the data from one server to the other. This takes even more time to do. It is a not a trivial project, no matter which way you do it.
