I'm afraid what you are asking for doesn't exist.

There are also several different Methods of 'upgrades' and the steps vary widely.

The steps also vary depending on what features and products you are using.

They also vary based on the version you are upgrading from.

For a simple database on the same server I would suggest you look at using DBUA:  Database Upgrade Assistant.

The online docs for have the upgrade information for most methods.

You can also look at the reference guides at Oracle Support:

Master Note For Oracle Database Upgrades and Migrations (Doc ID 1152016.1)

This document links to at least a dozen other related documents talking about minimizing risks, minimizing downtime and describing different methods of performing the upgrade.

This is a very good task to test thoroughly before attempting it on a production database.  It is very possible to leave your database in an unstable state if you do something mid-process to screw it up (I have done it before and had to revert to backup and start over).
