We did an upgrade from 5.4 to 6.2. I used a copy (SAN trick) for the source of the upgrade. I do not think the 5.5 to 6.2 upgrade changed the copy, I did not check, but I did not see any writes to the disks. The extract was written to a new disk. We created a new devclass (file) to write the data to. Our about 200GB DB took about 3 hours to extract, the insert to 6.2 took 10+hours. This was done on a P6. We did 3 practice upgrades for each server. Only 1 upgrade test failed because we did not get a clean copy.
You might consider 6.2.5 as your target. Good Luck.

Reading the upgrade guide, I have to do the Dsmupgr prepared Then a Dsmupgrd extractdb I have not yet determined whether these will render the 5.5.4 server unusable? Has anyone out there done this and if so, what should I expect? Gary Lee Senior System Programmer Ball State University phone: 765-285-1310
