Migration checklist

After the migration process is completed, the dbMigration_x.log is created in the logs directory.

The x is incremented by one each time the migration process is executed.

This file logs all activities during the upgrade process. Each line in this log contains either the letter I or E. The I stands for informative and the E stands for error. Search for the pattern E to identify issues during the update. The search highlights the errors, if any.

You can ignore these errors that may have occurred during data migration:

  • java.sql.SQLException: There is already an object named
  • java.sql.SQLException: There is already an index on table
  • java.sql.SQLException: Violation of PRIMARY KEY constraint
  • java.sql.SQLException: Cannot insert duplicate key
