Migrating from an earlier version of Fault Analyzer

Information about migrating from an earlier version of Fault Analyzer is provided in these topics.

See Maintaining Fault Analyzer for information about the SMP/E installation and subsequent activation of the new version of Fault Analyzer.

The following information is applicable to all versions of Fault Analyzer.

LPA module compatibility

Fault Analyzer provides downward compatibility between load modules in the IDI.SIDIALPA data set. Hence, you can install a later version of Fault Analyzer, perform IPL with CLPA, and use these LPA modules with an earlier version of Fault Analyzer in LNKLST or STEPLIB.

All data sets in the STEPLIB concatenation must be APF-authorized for the Fault Analyzer 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 Fault Analyzer installed.

IDICHKI report

To ensure that important settings and exits are carried forward from an earlier version, you might want to create an IDICHKI 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).
