I came to a new shop at this time last year. Me predecessor did all of the heavy lifting to install z/OS 2.4. Basically, I had to do a little customization, and roll 2.4 into TECH, DEV, and PROD. Fortunately my predecessor documented everything he had done, which made my job much easier. His documentation regarding /etc & /var showed much the same information that Mark Zelden shared earlier, up to showing the output of the diff commands.
To answer your question, my predecessor started with the virgin 2.4 /etc and /var and applied all of the changes from the previously customized z/OS 2.2 /etc and /var.
