Your data is unique compared to anyone who has tested.
You need to find a way to set up Red Hat 5 some place else, clone, and test.
I don’t know whether you can flat line the new server, do that, and then revert
to Red Hat 7 (or re-install). The degree of difficulty probably varies if you
have a lot more than just Red Hat 5 on the existing server or if you have a lot
of vendor installed extras in the destination Red Hat 7.
But my point is that when different data is involved you can at most abstract
from someone else’s experience that “It hasn’t not worked yet.”

Subject: 12c running Pre-Upgrade script
Hello
I have to upgrade a couple of databases in Oracle 11.1.0.7 Linux 32 bit to
12.1.0.2 Linux 64 bit, the source runs in Red Hat 5 and target will be running
in Red Hat 7. Source is a server and the target is another server.
One of the first steps is run the pre-upgrade script from 12c in the source
Oracle Home, the 11.1.0.7 Home. This means that I have to run the preupgrade in
the production 11.1.0.7 database. Does anyone know if this can cause any
undesired effect in the production database? Also how many times we can run the
preupgrade script in the same database?
The reason is that i cannot install 11.1.0.7 32 bit in the new RHEL 7 server
because it is not supported so i cannot test the pre-upgrade step in the new
server.
Thanks
Alex
