Moving an Oracle database to a newer Oracle home

Moving a database to a new oracle home, owned by a different user and running a newer version.
NOTE : This is how is worked in my environment. It might not work the same in your environment. This is meant as a guide only.

1. Stop the databse
2. Change the ownership of all files.
   – include files in oradata, admin, and dbs folders
3. Edit the oratab file (to point the db to the new home)
4. Change to the new user
5. Set the ORACLE_SID
6. sqlplus “/ as sysdba”
7. Upgrade the database
