Note

  • From the Kyvos 2023.1 release onwards, the Derby repository will no longer be supported for Kyvos Manager. The only supported repository will be Postgres (either bundled or external).

  • In a fresh deployment using the Kyvos 2023.1 release, Postgres will be used as the default repository for Kyvos Manager. However, in cases where older releases were used to deploy the cluster, an upgrade will be mandatory to migrate from Derby to Postgres as the repository for Kyvos Manager.

  • If your environment has enhanced security, the managed identity must be granted 'joinViaServiceEndpoint/action' permission with the scope set to the virtual network in which Kyvos is running.

Note

If you have upgraded to Kyvos 2023.2, you must redeploy the Zookeeper using the Zookeeper configuration page in Kyvos Manager to switch to the latest version of Zookeeper. This is necessary for cloud and on-prem deployments to remove the previous version of Zookeeper.

If you're currently using the default Zookeeper on the Kyvos Manager node, you'll need to redeploy the ZooKeeper. This applies to any cluster deployed before the managed Zookeeper implementation and still uses the default Zookeeper on the Kyvos Manager node.

  • For Kyvos Manager: If you are upgrading only Kyvos Manager, it is necessary to redeploy Zookeeper immediately after the upgrade.

  • For Kyvos: If you are upgrading both Kyvos Manager and Kyvos using either the single click upgrade or the All components upgrade, you must redeploy Zookeeper after upgrading Kyvos Manager.

You must restart Kyvos services once the redeployment of Zookeeper has been completed.

Upgrading Zookeeper for Kyvos 2023.2

...

Switching to the previous version of Zookeeper

To access the previous version of the Zookeeper, perform the following steps. 

  1. Add the previous Zookeeper version bundle to the Kyvos Manager repository at  kyvosmanagerdata/server/repo/ .

  2. Take a backup of the new version 3.7.1 bundle of Zookeeper at a different location outside the Kyvos Manager repo. This bundle will be necessary for switching to the new version 3.7.1 of Zookeeper.

  3. Update the previous version bundle name in the supportedBundles present in the kyvosmanagerdata/server/repo/metadata.Kyvos/zookeeper.json file by deleting the new zookeeper version bundle name and then redeploy the Zookeeper to restore managed Zookeeper to version 3.6.1.
    For example, to switch to Zookeeper version 3.6.1, before uninstalling the Zookeeper, a key having a value like supportedBundles : [zookeeper-3.7.1.tar.gz] must be updated with supportedBundles : [zookeeper-3.6.1.tar.gz]

Switching to the default non-managed version of Zookeeper

To restore the default non-managed version of Zookeeper on the Kyvos Manager node, which was removed during the uninstallation of Managed Zookeeper, you will need to manually install Zookeeper on the Kyvos Manager node.

Upgrade Graviton JRE for AWS cluster

  • From Kyvos 2023.3 onwards, logs of Kyvos Manager Tomcat Server will be generated in the kyvosmanagerdata/server/tomcatLogs path. If you rollback Kyvos Manager to an older version, logs will be generated inside the kyvosmanager_war/kyvosmanager/logs/ folder of the Kyvos Manager on which the rollback was performed.

  • In case of a Rollback, the previous state of Kyvos Manager is restored. In case you made any changes that you need in the previous state, you need to perform them again.

Note
You don't need to manually remove the Derby derby jar from the latest kyvosmanager/webapps/kyvosmanager/WEB-INF/lib/ folder. This is because it's automatically migrated deleted after the database migration. Moreover, the Derby jar has vulnerabilities, therefore Kyvos Manager will delete it from the lib folder.
