About Migrating Alarms and Events Data

If you are upgrading to the latest version of Historian, and you have already collected alarms, you can migrate the alarms and events data after upgrading to latest version of Historian. Only after you migrate the data, you can retrieve alarms.

Note: Before migrating alarms and events data, ensure that you have backed up the data.

To migrate your alarms into the new alarm database, you must back up the old alarms, and restore them into the new database. You can back up the data before the upgrade using Configuration Hub or Historian Administrator, or you can back up the data after the upgrade using the Proficy Alarms Database Migration Tool.

You may need to migrate small time periods if you have many alarms. If you need to migrate the alarms in blocks of time, do the oldest alarms first.
