Steps to Reproduce

Run upgrade of rules schema from PRPC 6.3 to Pega 8.1.4

Root Cause

A defect in Pegasystems’ code or rules. The rule-file-text instances which do not have a ruleset version set are present.


Perform the following local-change: 
  1. Identify and remove rules which have a null pyrulesetversion from the pr4_rule_file table. Readd the rules after the upgrade if they are required
  2. Delete .PR4_RULE_FILE  where pyrulesetversion=null from the rules
  3. Resume the upgrade
