Re-create a graph store in primary-standby mode after upgrading ArcGIS Enterprise

Description

The ArcGIS Data Store 10.9.1, 11.0, and 11.1 graph stores are created in single-instance mode and only support a single machine. Upgrading the graph store to ArcGIS Enterprise 11.2 and later does not change the deployment mode to allow for more than one machine.

Cause

The underlying technology used for the graph store does not support changing deployment modes.

Solution or Workaround

1. Follow the instructions in each ArcGIS Enterprise component’s installation guide to upgrade all components of the ArcGIS Enterprise deployment.
   Use the links on the Installation and Deployment page and the Other versions menu in each installation guide to access instructions for each component for the operating system and version required.
2. After finishing upgrading the deployment, create a backup of the graph store:

backupdatastore <backup file name> --store graph –location <location options>

See the ArcGIS Data Store utility reference page for syntax.

Note:
You must create a backup after upgrading; you cannot use a backup file of an older ArcGIS Data Store version to restore the graph store.

3. Remove the existing graph store machine from the hosting server.

unregisterdatastore --stores graph

4. Install ArcGIS Data Store on a new machine, but do not proceed with configuration.
5. Use the backup file created in Step 2 to restore the graph store to the new machine using the following syntax:

restoredatastore –store graph –target <backup file name> --source-loc <parent directory location of backup file> --data-dir <Data Store content directory on new machine>
 --server-url <hosting server URL> --server-admin <username of ArcGIS Server administrator of the hosting server> --server-password <password of ArcGIS Server administrator of the hosting server>

See the ArcGIS Data Store utility reference page for an explanation of each operation.
This creates a graph store, which is deployed in primary-standby mode by default.

6. Install and configure the graph store on a second machine to make the graph store highly available.
