Hello Our backup-server will be upgraded to TSM 4.1.x (eg.2 i think) next week. I don't think all clients will be upgraded to the same level by then. Some of them have 3.1.x-clients - especially some NT4.0 clients. Are there any major conciderations/problems that I should be aware of in that situation ? Are there anything that will not(!) work ? - or are there only that I can't use the new/extra features of the 4.1.2-clients ? Some of the NT4- and Win2000-servers (nodes) are my special concern. I'll be happy for all hints and tips (Warnings ?).
