RE: ZERO Database Downtime???

Heck I don't know.

Because the migration documentation says to do it the other way? Upgrade the software and then upgrade the data dictionary?

I'm assuming that it might be a bad idea to have upgraded OS software without the matching upgraded data dictionary components.

Maybe that's a bad assumption - buts that's always the way Oracle has said to do it.

Why wouldn't you upgrade all instances to the latest version first, then

apply the database upgrade after all instances are up?

This would allow for no database downtime.
