Yes.

If you are moving from an AIX system to another AIX system (I don't know
what a Nighthawk is except in the ornithological sense), you can simple
restore the database from one of the systems to the new system.  That takes
care of half your clients.  I would then register the clients from the other
system on the new system, change their options files to point to the new
server and let them do their full backup again.  You won't have any of the
old data on the new system, but you will have all the new.  How to get the
old?  Two ways: keep the old server around until all the data expires or
export the client data and import it on the new server.  Number one is much
easier.  Export/Import can be a lengthy process. You can also "keep the old
server around" by installing a second instance of the server on the new
system.  Lots of things to consider if you choose this, but it will work.

If you are moving from one OS to another, you can only do the export/import.
You cannot restore the TSM database backup taken from one OS to another.
