Your impressions are wrong? There is little to no database upgrade when going
from 6.3.2 to 6.3.3. Technically the 6.3.3 upgrade does have a database upgrade
but if you forget to do it, nothing bad will happen. All it does is upgrade the
core_data to say 6.3.3 (instead of 6.3.2). When going to 6.3.4 though, there is a database upgrade.
Hence you'll see docs there called:
Upgrading BladeLogic to 6.3.4 (Oracle)
Upgrading BladeLogic to 6.3.4 (SQL)
My mistake - I was confusing this with not having to go from 6.3.2 to 6.3.3, and how we can upgrade directly from 6.3.2. to 6.3.4. All set now.
