My sysadmins prefer a new install over upgrade in some circumstances such as
when they suspect there is "baggage" of some sort such as a very old
machine/Linux version.
Not sure on /var/oracle, but make sure you have a backup ... maybe separate
mount is good enough?
For Oracle database, you'll want to
- verify existence of proper/minimal packages and kernel parameters (see
MOS note
169706.1<https://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id9706.1>or
the installation doc for your database version installation).
- relink stuff in the Oracle Home (see MOS note
131321.1<https://supporthtml.oracle.com/ep/faces/secure/km/DocumentDisplay.jspx?id1321.1>
).
