Simplified Upgrade from 9.1 to 9.2
We are planning to upgrade from 9.1 to 9.2. We went through the below document. https://docs.oracle.com/cd/E61420_01/EOUUO/installation_workbench.htm#EOUUO00007
But we did not find any steps where it explains how the .c and .h files of old release are moving to new release.
Any document or suggetions is appreated.

Tarani
