CQS automatic structure checkpoint fallback considerations

You can fall back from a common queue server (CQS) that can perform automatic structure checkpoint to an earlier version of CQS.

To fall back from an IMS 15 CQS that can perform automatic structure checkpoint to an IMS 14 or IMS Version 13 CQS, you must remove or comment out the STRCHKPT parameter in the CQSSLxxx member of the IMS PROCLIB data set.
