Summary

Learn what to do when your migration fails with the error Caught BatchUpdateException for insert into "public"."AO_6FF49D_MIGRATED_FILE".

Overview

When migrating projects from your Jira On-premise to the cloud with the Jira Cloud Migration Assistant (JCMA), the projects can fail with the above error message.

The signature below can also be seen in the application log file atlassian-jira.log.

ERROR	[c.a.j.m.tracking.polling.Poller] xxx-jiraProjectUpload#8xxx: task worker xxx failed to process Task(migrationId=xxx, migrationTask=com.atlassian.jira.migration.orchestratorclient.tasks.ProjectTransferMigrationTask@7xxx[projectId=10000,heartbeatUrl=https://api-private.atlassian.com/migrations/v1/migration/xxx], cloudSite=AO_6FF49D_CLOUD_SITE {CLOUD_ID = })
com.querydsl.core.QueryException: Caught BatchUpdateException for insert into "public"."AO_6FF49D_MIGRATED_FILE" ("FILE_SERVER_ID", "FILE_MEDIA_ID", "MEDIA_CLIENT_ID", "MIGRATED") values (?, ?, ?, ?)

  	Detail: Key ("ID")=(1) already exists.

Duplicate key values in the table AO_6FF49D_MIGRATED_FILE_pkey are a typical result of the previous migration data conflicting with the current migration.

When this happens, it is recommended that a clean start is made by reinstalling the JCMA on the source site.

Solution

1. Uninstall the app:
   1. Navigate to Apps > Manage apps.
   2. Spot the JCMA app in the list.
   3. Click Uninstall.
   4. A notice appears indicating that the app was successfully uninstalled.
2. Stop the Jira On-Premise instance (Start and Stop Jira applications).
3. Back up your database.

4. Run the following commands on your Jira On-Premise database to obtain new commands:
   
   PostgreSQL

   SELECT CONCAT('DROP TABLE "', table_name, '";') FROM information_schema.tables WHERE table_name LIKE 'AO_6FF49D_%';

   
   MySQL
   

   SELECT CONCAT('DROP TABLE "', table_name, '";') FROM information_schema.tables WHERE table_name LIKE 'AO_6FF49D_%';

   
   MSSQL
   

   SELECT CONCAT('DROP TABLE "', table_name, '";') FROM information_schema.tables WHERE table_name LIKE 'AO_6FF49D_%';

   
   Oracle
   

   SELECT CONCAT(CONCAT('DROP TABLE ', table_name), ';') FROM USER_TABLES WHERE TABLE_NAME LIKE 'AO_6FF49D_%';

   
   
   
5. Run the commands resulting from the previous step to drop the JCMA tables.
6. Start your Jira On-Premise instance (Start and Stop Jira applications).
7. Reinstall the JCMA app (Install the Jira Cloud Migration Assistant).
8. Retry the migration.
