Recently I did also a migration of an ADSM 3.1 to an TSM 5.1 at one of our
customers. I did not have to migrate the database because they decided to start
from scratch with this new environment (other box, other robot, other TSM). Some
of the clients did not accept the TSM 5.1 client because of operating system
problems so for these servers I installed the latest supported client which was
an TSM 3.7 and until now no problems were encountered.
