I agree with Xav, this is something you want to do with a partner that has done this kind of stuff before. There are all sorts of things that need to be sorted, if you really need to migrate the TSM db you need to upgrade to 5.4 or 5.5, then you have the issue of LTO-5 not being able to read LTO-1 tapes so you need to (for example) connect both libraries, make new storagepools etc etc.
But there also might be another route, the let most of the data die on the old system, migratie via server-to-server what needs to be saved and start over, that way you don't have that much work on the old evironment (you do need to upgrade TSM) and it's not such a big-bang migration. However you do this, it's going to take a some solid preparation and planning. Make sure you get somebody that has good TSM 5, TSM 6 and LTO tape skills.
