We defined a lot of rules using Drools 5.5.0. Since Drools 6 has been released, we used "drools-wb-jcr2vfs-migration" script to migrate the repository from 5.5.0 to 6. The script generated exception during execution. It said modules migrated. But when migrating categories, it fails. Hope to seek advice. Below is the output with errors: D:\Austin\drools-wb-jcr2vfs-migration-core-6.0.0.Final\bin>runMigration.bat Migration started.
