-Nothing you do with TSM, I mean NOTHING, will result in data loss, if done correctly.
-The whole POINT of TSM library sharing is so that you don't have to partition the library; if you partition the library you can't share the drives dynamically between the TSM instances. -Splitting the clients between different servers can be tedious; as noted by others, you may need to do exports if the client data is long-lived. (Look at letting the client backup data expire where practical, and just moving archive data - that can reduce the work a lot.) BUT, setting up library sharing is very easy. -The problem is clearly too complicated for your contractor, rather than too complicated for your TSM!
