I thought the DIR_WS_ADMIN was supposed to stay as-is. I just wanted to check on that.

I did upload the changed files and set the permission to 444 (read-only). I also made the new directory (XYZ123) and copied everything to it with this:
cp -rv * ~/sitename/zen/XYZ123

I then checked the files and all copied correctly. I then renamed the admin folder as a backup folder.

When I login to my admin account I goto: http://www.site.com/zc/xyz123/
I then enter my admin user name and password. It logs in fine.

When I go to the menus, like TOOLS -> DEVELOPER's TOOLS, the link still points to http://www.site.com/zc/admin/

Is there something I'm missing here?
