Is it that the procedure described in Oracle documentation is the path organizations usually follow to upgrade/migrate their databases? Or is it a customized approach?
Can you point to manuals/documentations on real-life database upgrading/migration?
For your upgrade, I strongly recommend reading this guide until you are familiar with the upgrade process. Each upgrade I have ever done uses the information in this guide for the upgrade process.
