If you must fall back from Version 15.0 to Version 14.0, you can do so by executing the following jobs. This process performs a soft fall back meaning any changes to the CXX/DD/DDD are preserved with any modified SQL objects after Version 15.0. We recommend this process. If for some reason this process fails and you must go back to Version 14.0, use member BDUPG03R to fall back and only as a last resort. The BDFBK* members are recommended for fall back, not BDUPG03R.
For more information about Directory (CXX) Upgrade and formats, see the CA Datacom Release Notes and CA Datacom/DB DBUTLTY Reference Guide.
For this phase, run the INSTJCL library members whose names start with BDFBK.
