Two new labs have been added to the Proxmox VE 8 courses that teach the upgrade to Proxmox VE 9 step by step:
- Proxmox VE 8: Setup and Management, Lab 16, Upgrading a Proxmox Node to PVE 9: upgrade an individual server from VE 8 to VE 9
- Proxmox VE 8: Advanced Administration and Optimization, Lab 15, Upgrading a Proxmox Cluster to PVE 9: upgrade a VE 8 cluster to VE 9
Rehearsing the upgrade in a lab surfaces the version-specific steps (repository changes, package transitions, node sequencing in a cluster) before you run them against systems your classes depend on.
On NDG Online
The labs are live now in Proxmox VE 8: Setup and Management and Proxmox VE 8: Advanced Administration and Optimization, with nothing to set up.
On NETLAB+
The same labs ship in the VE 8 lab libraries: Setup and Management and Advanced Administration and Optimization. Update the Advanced Administration and Optimization course in the Course Manager to Release 3 to receive Lab 15; details are in the Proxmox content release notes.
Upgrading your own system
The labs teach Proxmox upgrade skills; NETLAB+ administrators upgrading their system's Proxmox backend should follow the NETLAB+-specific steps on the upgrade path to Proxmox VE 9, which also links the Proxmox VE 9: Setup and Management course for teaching the new version.
