If your store is truly running on ZC 1.3.8a, the best thing to do and not have so many potential commands to be concerned about would be to upgrade to the latest version of ZC. This would eventually require upgrading the php version to something more acceptable/secure, but don't do that until the test upgraded site is operational and the upgrade process can be duplicated at least once.

Suggested guidance to upgrade by rebuilding: http://www.zen-cart.com/entry.php?3-...d-of-upgrading
