Migrating from an earlier version of Z Abend Investigator

LPA module compatibility

Z Abend Investigator provides downward compatibility between load modules in the HFZ.SHFZALPA data set. Hence, you can install a later version of Z Abend Investigator, perform IPL with CLPA, and use these LPA modules with an earlier version of Z Abend Investigator in LNKLST or STEPLIB.

All data sets in the STEPLIB concatenation must be APF-authorized for the Z Abend Investigator data sets to retain their APF-authorization.

Sharing of history files across a sysplex

There are no issues with sharing of history files across a sysplex with a mix of supported levels of Z Abend Investigator installed.

HFZCHKI report

To ensure that important settings and exits are carried forward from an earlier version, you might want to create an HFZCHKI report on the earlier version, and again after the later version has been installed. Compare the reports to identify any differences. For details, see Step 3: Verify the service level (optional).
