Upgrade the Historian version

Refer to Upgrade from a previous version of AVEVA Historian to see which versions can be directly upgraded to Historian 2023 R2 SP1.

The existing Runtime and A2ALMDB databases are automatically migrated to during the installation, preserving all existing settings and tag configuration.

History blocks created using a previous version of the Historian do not require any migration and can be copied to and used with Historian 2023 R2 SP1, as long as the tags they contain are present in the Runtime database.

To upgrade the Historian

1. Back up the Runtime database.

2. Shut down and disable the Historian using the Operations Control Management Console. Any remote IDAS nodes will go into store-and-forward mode.

3. Run the System Platform installation program to perform the upgrade. For more information, see Upgrading the Wonderware System Platform.

4. The installation program detects the previous version of the Runtime database and prompts you to keep the existing database or recreate the new database.

5. If you re-create the database, the existing Runtime database will not be renamed but will be overwritten with a new Runtime database. If you do not re-create the database, the existing database will remain intact.

6. Finish the installation of the Historian.

7. Restart the computer.

8. Start the Historian. The Historian will start acquiring and storing the store-and-forward data from the existing remote IDASs.

9. After the Historian Server node is upgraded, you can upgrade any remote IDAS nodes.
