Jeff,

Yes, I did encounter a problem once. with migrating from 8.0.4 to 8.1.6. From that point on, I don't want to take any chances, because, what happen was when I spoke to oracle, I mentioned that I migrated to 8.1.6.2, their first question was how did you migrated, and after hearing my story, their reply was go back and start at the base and then apply the patch. IT all worked after that and I was happy.

From that time, I'll spend some time more in following things step by step, rather than going back to re-do things with the agonny
