Migration fails with following error:

[INFO ] [Backup] Restoring management node from backup...
ERROR 1062 (23000) at line 18637: Duplicate entry '' for key 'PRIMARY'
[ DIE ] [Backup] Unable to restore dump.


Duplicate records in some database on the source server.


  1. Unpack the backup archive hspc-mn-backup_2000.01.01.tar.bz2

  2. Check mysql dump file: vi +18637 ./tmp/db_dump.sql (+18637, because the line is specified in the error)

  3. Check the request for duplicate records. Then go up in the file and note the database those records belong to.

  4. Make a dump of that database on the source server.

  5. Remove duplicate records from the appropriate database on the source server.

  6. Repeat migration attempt.
