Generating a comparison transaction

A comparison step must be performed and validated before importing the contents of the Inbound Migration file.

  1. Select Maintenance > System Administration > Data Migration > Migration Import > Inbound Migration.
  2. Locate your imported migration in the list.
  3. Click the Compare button next to the migration to be compared.

    • If a comparison is already scheduled or in progress for this migration, this message is displayed:

      Comparison for migration {X} has been scheduled already.

    • If scheduling is successful, this message is displayed:

      Scheduling comparison for migration {X} was successful.

  4. To review the results after the comparison is completed, select Maintenance > System Administration > Data Migration > Migration Import > Migration Import Transactions.
  5. Find the transaction of type COMPARE for your migration.
    Status types that can be displayed include:
    • COMPARED: Comparison found differences
    • EMPTY COMPARISON: No differences found
    • COMPARISON FAILED: An error occurred
  6. Ensure that the comparison transaction is valid, meaning:
    • There were no errors during the comparison.
    • The comparison is not empty, unless you expect no changes.
    • No new data has been inserted or changed in the database since the comparison. If the database has changed, you must run the comparison again.
    • The comparison is not outdated. Check for warnings about the comparison being older than the configured validity period.
