Hi

We attempted to upgrade from 7.9.2 to the latest version 8.4.2.36762 recently and encountered this error.

We’re using Oracle as our database. I’d appreciate any pointers even if we can manually workaround. Also should we have upgraded to an intermediary version first as I thought the upgrade process handled this

Thanks

Hello,
There is a constraint named pk_active_rule_parameters in the table active_rule_parameters that should have been deleted before being recreated with the same name.
You can try to drop that constraint (and associated trigger/sequence if any) before continuing the migration.
Make sure you have a backup of your DB.
