Migrating Classic Historian Data to Your Historian Database
About this task
Note: When migrating data, Classic Historian nodes must be online with a loaded database so that descriptions and EGU values are retrieved. If the Classic Historian nodes are not online with a loaded database, the migration utility will create tags that may have incorrect descriptions and EGU values.
To migrate Classic Historian data into the Historian:
Procedure
- In Classic Historian, select the Historian Migration Button, shown in the following figure, to open the Historian Migration Utility.
- Select Configure Options from the Options menu.
- Enter or modify any specific configuration information. For more information, refer to the Configuring Classic Migration Options section.
- Select Migrate Collection Groups from the File menu. The Utility prompts you to specify if you would like to migrate all groups. The Historian Classic Migration Utility connects to the specified server and migrates the groups.Note: When migrating groups, Qualifier and Phase parameters are not migrated. If a group is not active, it is still migrated to the Historian. Groups are not preserved in Historian. All tags are added to Historian with the collection rate for the group.
- Select Migrate Historical Data from the File menu. The Select Historical Data File(s) window appears.
- Select one or more historical files and select Open. The Migration Utility attempts to migrate all selected historical data files. The title bar displays the current file status (1 of 5, for example). Refer to the Migration Utility main page for information on the progress of the migration and any encountered errors.Note: The Migration Utility page only displays the most recent lines of the log file. For the full set of logged messages, refer to the log file, typically located in C:\Program Files (x86)\GE\iFIX\Local\iFIX2IhMigration.Log.
