We rolled Traveler 8.5 out to our sales force this summer as a cost saving measure. Testing worked fine, pilot group worked fine, for over a month but then when we got into the bulk of the users the server either couldn't handle the load or it was just bad code or both... we needed 3 or 4 fixpacks, some of them very recently created to get it going fine. (some of them made it into the recommended Traveler fixpacks after installing).
Anyhow...after this not so great experience we are a bit hesitant to upgrade the server to 8.5.1 - anybody had experiences with that? Any pitfalls? Anything particular we should be aware of?
