Graph Studio Upgrade Notes

If you are upgrading Graph Studio from a previous release, review the following notes for important details about upgrades to Graph Studio platform components.

• Review Your License when Upgrading Between Major Versions
• Upgrade the Graph Studio Unstructured Leader and Worker Nodes
• Upgrade Any CData ODBC and JDBC Drivers
• Updating the Graph Lakehouse Graph Data Interface Extension

Review Your License when Upgrading Between Major Versions

If you are upgrading to a new major version of Graph Studio, such as from 4.x to 5.x, your Graph Studio license may need to be updated to add the new version. Before upgrading between major versions, contact Altair to review and update your license if necessary.

Upgrade the Graph Studio Unstructured Leader and Worker Nodes

Updates to the Graph Studio server typically include changes to the Graph Studio Unstructured (AU) cluster software. If you are upgrading from a previous release, upgrade the AU worker and leader nodes to the latest version. For instructions on upgrading an AU cluster, see Upgrading Graph Studio Unstructured.

When upgrading the AU software, the leader and worker applications must be upgraded at the same time using the same installer so that the software versions are identical across the cluster. You cannot upgrade the worker nodes without upgrading the leader and vice versa.

Upgrade Any CData ODBC and JDBC Drivers

Updates to the Graph Studio server often include improvements to the CData ODBC and JDBC drivers. To take advantage of the improvements, Altair recommends that you upgrade any existing ODBC or JDBC drivers with the latest version after upgrading Graph Studio.

Updating the Graph Lakehouse Graph Data Interface Extension

If you do not upgrade Graph Lakehouse when updating Graph Studio, and Altair Support recommends that you update the Graph Lakehouse Graph Data Interface (GDI) extension for your existing installation, you can follow the instructions below to replace the existing extension. Your Customer Success Manager can provide the new gdi-<version>.jar file.

1. Download the gdi-<version>.jar file provided by Altair to the Graph Lakehouse leader server.

2. Remove or move the existing GDI .jar file from the <install_path>/lib/udx directory on the leader server.

3. Copy the new gdi-<version>.jar file to the <install_path>/lib/udx directory on the leader server.

4. Run the following command to change the owner of the file to the anzograph user:

   chown anzograph:anzograph -R <install_path>/lib/udx/gdi-.jar

   For example:

   chown anzograph:anzograph -R /opt/cambridgesemantics/anzograph/lib/udx/gdi-4.0.0-202205280158.jar

5. Restart Graph Lakehouse to apply the update.
