Work Notes will be cleared on existing Problem records after Problem Migration tool plugin is installedIssue Work Notes get cleared/emptied on existing Problem records after activating the Problem Migration tool plugin.CauseWhile migrating, the plugin uses setWorkflow(false) and applies it to all Problem records irrespective of their state.ResolutionThe feature is designed to use setWorkflow(false) to avoid all related Business Rules or other scripts to trigger running and cause issues during migration. Existing Work Notes will be cleared, but after migration they will be re-added with past date as 'Problem record is being migrated...'. These notes will be added with the name of the user who originally created the existing problem record.Related LinksReview the TOI for more information on work_noteshttps://trainingops.servicenow.com/detail/video/6155408404001/technical-support:-servicenow-store:-itsm---sr-itsm-problem-management-migration-utility-v1.0-may-2020?q=problem%20migration%20utility(Around 41.45 mins and at 51.08 mins)
