Bob,
I've no personal experience of V6 as yet. But, we upgraded from 3.5
direct to 5.0 almost as soon as it came out. If history repeats itself
you would do well steer clear of V6 for now - we weren't really happy
with 5.0 until 5.0.2.6 The bugs in 5.0 didn't help when we were trying
to solve application issues resulting from the upgrade (JVM and J2EE
changes).

Thanks Walker
I see that WAS V6 is about 6 months old now with 2 REFRESH packs since
GA. V6.0.2 has 115 items listed at:

In contrast, WAS V5.1 is about 18 months old now with 2 CUMULATIVE
fixes since GA.

Our inclination is to stay off the "bleeding edge" for now, and to
accept the additional costs (train, plan, develop, QA, implement)
associated with two upgrades compared with one big upgrade. Qualitative
risk analysis is a tricky beast!

Thanks again for your input.
Bob
