Step F8: Control-D and Control-V fallback

1. Restore the Control‑D and Control‑V Repository.
   1. Restore the User Reports List files

      To restore the User files, use the CTDUFDUL job from the CTD JCL library to unload the files from the current release. Use the CTDUFRST job to restore those files to the previous version.

      Note: If you use the same naming convention and IOA QNAME for User Reports List files in both the previous version and current version, you may omit this step.

   2. Format the Active Missions file of the previous version of Control‑D using the FORMAMF job in the previous IOA INSTWORK library.
   3. Format the Active Transfer file of the previous Control-D version using the FORMATF job in the IOA INSTWORK library of that version.
2. The Control‑D mission definition members of the new version are not usable by the earlier version. Therefore, you must use mission definition members of the previous version. If you changed these members in the new version of Control‑D version, reapply the changes to the members of the previous version.
3. Adjust Date Control records.

   Copy all date records (meaning, all members that start with the DDAT prefix) from the new version Control‑D PARM library to the previous Control‑D PARM library.

4. Ensure that the security definitions that were used in the previous version are in effect.
