We strongly recommend to back up KSMG virtual machines (make a snapshot of the virtual machine in the hypervisor) of all cluster nodes before upgrading KSMG. This will let you go back to the previous version of KSMG if the installation of the new version fails.
Before upgrading using the KSMG web interface, you must download the ZIP archive with the upgrade package from the Kaspersky website or a partner company website and extract the KTGZ update file from the archive.
This sequence of steps lets you keep processing the traffic of the organization during the update process.
To update the application to version 2.1 in a cluster containing multiple nodes:
- In the web interface of the Control node, go to the Nodes section and make sure that all cluster nodes are available and do not have errors.
If there is no access to the cluster node, or if errors are encountered on the node, resolve the problems before you start the update process.
- Install upgrade packages on one of the Secondary nodes.
After installing the upgrade package, the node becomes inaccessible to other cluster nodes. In the web interface of this node, you need to assign it the role of the new Control node.
- Install upgrade packages on each of the remaining Secondary nodes.
After the update, each Secondary Node will be accessible to the new Control Node and inaccessible to the old Control Node.
- Install upgrade packages on the old Control node.
Before installing the update, you must assign the Secondary node role to it in the web interface of this node.
As a result, all cluster nodes are upgraded to KSMG version 2.1 and are accessible from the new Control node.
If necessary, give back the Control node role to the node that previously was the Control node.
