Upgrading to 26.1.0

To update an already installed OFS MMG Application, perform the following steps:

Prerequisites:

• A valid working setup must be available before performing the upgrade.
• Use the MMG Config Schema, MMG Graph Schema, and MMG Datastudio Schema, from the existing version, along with the wallet configurations.
• Shutdown all the services of the existing installation by using shutdown.sh.
• Backup the existing OFS MMG Installation to a backup folder.
• Upgrading to 8.1.3.0.0 and above (including 26.1.0 and later releases) require MMG 8.1.2.7.x or higher versions. The installation will fail if the prerequisite is not met.
• OFS MMG DTP must be created.

Upgrade:

Follow steps mentioned in the Installation section.

After upgrading to OFS MMG 26.0.0, if you see the error {{PKIX path validation failed: java.security.cert.CertPathValidatorException: signature check failed.}} in the OFS MMG server log, Data Studio log, or notice that the Data Studio (DS) health checks are failing in the UI, it means that the required SSL certificate is missing from the Java keystore. To resolve this, re-import the Data Studio server certificate into the Java keystore used by OFS MMG and then restart the OFS MMG services. This will restore the secure connectivity between OFS MMG and Data Studio.

Note:

Compare and copy the placeholder values from the existing installed MMG.config.sh to the new one mentioned in the Installation section.

Note:

To ensure that the latest OFS MMG application and its dependent packages are reflecting correctly, all the Conda environments must be upgraded after the successful installation of the latest OFS MMG application.

This can be done by activating the Conda environment and executing the ./python_env_install.sh script that can be located in OFS_MMG/bin.
