How do I know if we have customized help files?
Help files will be maintained in the database and would not be on the filesystem.
How do I know if we have customized forms with Oracle Forms 6i
This is a bit more difficult, but since you are 12.0.6 then you are already using forms 10.1.2 so no need to upgrade the forms
You can also use our comparison tools to help discover customization's. You can use the File comparison report to help find custom forms.

How do I backup the source code so I can re-create it later
You will want to keep your 12.0.6 for a bit in case you need to go back to it for missed customization's.
All source code for custom packages and such are stored in the database, dba_source table, so you can access it from there.

The plan will be, do the upgrade and skip the activity above? and let the users found out the errors later, when end-to-end testing is done.
Will this practice be okay?
That is how many customers who have old legacy customization's do it when the original developers are all gone. Everything should get flushed out during your first pilot testing.
Thanks Kanda, David, and ALL,
I will check that docs...brb
