Error encountered while upgrading to pega 8.8.1 from pega 7.4
Hi,
We have encountered an error while running upgrade.sh script.
[java] 2023-03-14 17:57:06,129 [ main] [ ] [ ] [ ] ( internal.loaders.FastLoader) ERROR - Encountered batch element exception: [java] org.postgresql.util.PSQLException: ERROR: duplicate key value violates unique constraint "pr4_rule_vw_pk" [java] Detail: Key (pzinskey)=(RULE-ADMIN-SYSTEM-SETTINGS PEGA-PROCOM BULKPROCESSTRANSFERFLOWACTION #20141110T145849.091 GMT) already exists. [java] at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2565) ~[postgresql-42.2.25.jar:42.2.25]
as it exists already it should be skipped, instead it is throwing the error.
