Bob, Don't bother. I can tell you from experience that it won't work, and Tivoli support will tell you it isn't supported. BTW, export/import isn't supported either, although it "may" work.
We are in the middle of a migration from AIX to HP (L2000 server). Tried the same thing. The problem is apparently in the way TSM records data on tape on AIX vs. on HP-UX.... TSM on HP-UX could not read the tape created on AIX. I was able to export the database and import on HP-UX. But, like you, we have a lot of node data on AIX (about 60TB). By my rough calculations, (using DLT7000 drives) it would have taken more than six months of exporting, 24x7, optimistically assuming a 5MB/sec throughput. What we are now doing is keeping our old TSM and library online until the "old" data expires.... which will be about a year. Then we'll export/import any remaining archives. Luckily for us, we have the hardware to do this. Some other folks have suggested FTP'ing the database from AIX to HP-UX....or 'tar'ing it... I didn't think of it, and now it's too late to try, since we've been backing up on HP for several months. I also didn't try the unloaddb/loaddb, but I suspect the same problem would exist.

It should work since the platforms are both UNIX (handling tape read/write sim.). Otherwise you'd unloaddb to a file and then move the file to the new platform -- maybe preferable anyway to re-optimize the database...
