Erik - I believe the upgrade / recovery manual will have the more concise definition you seek. Look for the Oracle version you are on and the one you want to move to and it will tell you whether you need to upgrade or migrate. With an upgrade you usually just bring up the new version and run some procedures to modify your system tables. With migrate it is much more involved. To put things concisely:

upgrade - good
migrate - bad

        upgrade - minor, easy.
        migrate - hard, difficult, headaches.

I cannot find a definitive definition of these two terms on metalink. Can these terms be used interchangeably or is there a difference?

Thanks
Erik
