I am just trying to upgrade our server to 5.3 even if I have tried not to do it for a long time due to the new interface, but now I have to since our new DELL ML6000 Taperobot is not supported in 5.2. In the readme file for 5.3 there are a note that only storage agents 5.2.3 and up are supported by 5.3 but what about agents for NT 4.0 there the latest one is 5.1.6?
