In-place worked very well using DBUA. Much lower downtime than if it were a 2-system upgrade, at least for our DBs. I've never trusted an Oracle wizard for anything in Production before this, so I was very happy that DBUA took a lot of the more complicated/confusing steps (e.g. timezone upgrade from V4) completely out of the equation, and did it very well. I was able to test the full upgrade of Production using another server, which was huge for some of the complexities, like needing to drop unused EE modules. GL!
