This is a video tutorial of a systems engineer at Verge IO demonstrating how to upgrade a two-node Verge IO cluster. The engineer logs into the system, navigates to the system update section, changes the branch, downloads the updates, and installs the updates. The upgrade process involves putting the first node into maintenance mode, migrating all the VMs to the second node, updating the first node, bringing the VMs back to the first node, and then updating the second node. The upgrade process includes updating the hypervisor, KVM, QMU, the management console, VSAN, and all services in the environment. The engineer shows that the upgrade process is successful and demonstrates that the environment is fully accessible after the upgrade. The entire process can be done quickly and efficiently in just a few minutes, includes no downtime and patching/updating is safe and easy.
