Migration Option
The Migration Options section allows you to select all or specific tagmasks and set the time range for migration
| Field | Description |
|---|---|
| Tagname Mask | Specify certain tags for migration only (NODE1:* for instance) or select all tags (*). |
| Starting Date | Select a starting date for migrating data. |
| Ending Date | Set an ending date for migrating data. Note: The Migration Utility migrates data up to but not including the specified Ending Date. Carefully select your Ending Date to ensure that you include all required data in the migration. |
| Configure New Tags As Required | Specify whether the Migration Utility automatically creates tags upon migration, or migrates data only for tags that already exist in the Historian tag database. This allows you to manually create the tags you want to migrate in Historian first, then run the migration only for those tags. |
| Use Tag Configuration from iFIX | Maintains tag specific configuration for iFIX tags. If you do not select this option, Historian uses its tag configuration default settings when migrating iFIX tags. For example, if you have an EGU set to 25-55 in an iFIX tag and you clear this option, the tag migrates with an EGU of 0-100. |
| Allow Updates to Existing Data | Allows Historian to replace data if data already exists for the tag at that timestamp. |
| End of Collection Marker | Write a bad data quality data point for each tag when the migration concludes. Select this option if you do not want your trend applications to display a continuous plot of the last good sample for that Historian tag. |
