Re: do you prepare documents when upgrading Oracle

The advantage in doing this specifically for your own situation is
- you are aware of any gotcha's and pitfalls beforehand
*****- you don't need to improvise at the actual migration, so you lessen the chance this will be the hour of your doom. (Just implemented a major change at a site, which was fully prepared)
- if you become ill, or are otherwise absent, anyone else can do it.
