HistorianReadback Options
Allows you to set the following options:
| Field | Description |
|---|---|
| Readback Values | Immediately read back samples after they are written. This verifies that the migration was successful. All samples that were written, including bad data quality and shutdown markers, are read back. Important: Selecting the Readback Values option puts additional load on the archiver and can slow the migration process. If samples are not found during the readback, the Migration Utility sends a message to the migration log file (\dynamics\local\ifix2ihmigration.log). It does not stop the migration. |
| Write Values to Server | The data writes and tag adds are written to the Archiver. If you want to perform a readback-only migration, clear this option and select the Readback Values option. This allows you to select a specific Classic historical file and perform a readback to confirm that all samples in the Classic file exist in Historian. If samples are not found during the readback, the Migration Utility sends a message to the migration log file (\dynamics\local\ifix2ihmigration.log). It does not stop the migration. |
