Sharing the CSD between CICS Transaction Server for z/OS, Version 5 Release 3 and earlier releases

If you want to share the CSD between CICS® regions at different release levels, to enable you to share common resource definitions, you must update the CSD from the higher level region - CICS Transaction Server for z/OS®, Version 5 Release 3.

• Use the ALTER command on definitions that specify obsolete attributes.
  This does not cause the loss of these attributes in CICS Transaction Server for z/OS, Version 5 Release 3, so you can safely update resource definitions from a CICS TS for z/OS, Version 5.3 region.
• If you are sharing the CSD between a CICS TS for z/OS, Version 5.3 region and a region at an earlier release of CICS, you can use the CICS TS for z/OS, Version 5.3 CSD utility, DFHCSDUP, to update resources that specify obsolete attributes.
  1. Specify if you want to use the compatibility option. Use the PARM parameter on the EXEC PGM=DFHCSDUP statement, using the option COMPAT.
     The default is NOCOMPAT, which means that you cannot update obsolete attributes. (See Figure 1.)
  2. You cannot use the EXTRACT command of the DFHCSDUP utility in this release when the COMPAT option is specified.
