We upgraded all of our SAP from 8.0.6 -> 9.2.0.3 last year, and had no concerns about whether it would work.

The reason we had no concerns is that we did *extensive* testing.

You have to commit to testing to do upgrades. Testing is more than 'the database came up and the app seems to work'.

There must be a testing plan. Production scenarios must be run, etc.
