How to update Proxmox VE from to the latest version 9.2.3 today

On May 21, 2026, it was announced in the forum the release of Proxmox Virtual Environment 9.2. This release focused heavily on platform refinement, stability, and core optimization. Therefore, in this article, we shall discuss how to update Proxmox VE from to the latest version 9.2.3 today. Please see Secure Boot 2023 Compliance Across WinPE, MDT, WDS, and ADK: Boot Chain Alignment and PXE Validation [Final Part], and how to Fix an error occurred while attempting to start selected VM on Hyper-V.

Proxmox VE 9.2 builds on the robust Debian 13.5 “Trixie” platform and introduces Linux kernel 7.0 as its new stable default. The release also delivers updated virtualization and storage technologies, including QEMU 11.0, LXC 7.0, and ZFS 2.4.

For software-defined storage, Proxmox now ships with Ceph Tentacle 20.2.1 as the default stable release, while continuing to offer Ceph Squid 19.2.3 as an alternative. Proxmox VE 9.2 also introduced several notable enhancements, including a new Dynamic Load Balancer to improve cluster-wide resource utilization, expanded Software-Defined Networking (SDN) capabilities with WireGuard fabric support, and fine-grained BGP/EVPN route filtering through route maps and prefix lists.

Administrators can now manage custom CPU models directly from the web interface, use the new High Availability (HA) arm/disarm functionality, and enroll Microsoft and Windows UEFI 2023 Secure Boot certificates through both the GUI and API. These improvements further strengthen Proxmox VE’s scalability, performance, and enterprise readiness.

Upgrade Proxmox v9.0.10 to 9.1.11

Unfortunately, this post remained in my draft folder longer than expected, and I was only able to publish it today. Since then, Proxmox has released additional updates, and the latest available version at the time of writing is Proxmox VE 9.2.3.

To ensure this guide remains relevant, I will demonstrate the upgrade process for both Proxmox VE 9.1.11 and the latest Proxmox VE 9.2.3 release. If you are on Proxmox VE version 8 to 9, this post will help you with the steps or “how to update Proxmox VE 9.0 now Supported by Veeam“.

Note: There are several ways to upgrade a Proxmox Virtual Environment (PVE) deployment to the latest 9.1.11 or 9.2.3 release. The approach you choose depends on your current version you are on, cluster configuration, and maintenance requirements.

Upgrade an Existing Proxmox

Since our node is already running Proxmox VE 9.0.10 and we wish to upgrade to 9.1.11, the upgrade is straightforward. Since this is a minor release update, you only need to refresh the package repositories and install the latest packages.

This is the recommended method because it preserves all existing virtual machines, containers, storage configurations, networking settings, and cluster memberships. You can also do this via the command line as shown below.

apt update

apt dist-upgrade

Proxmox also allows you to perform the same update through the web interface. To do this, navigate to the Node, click on “Updates”, and click on Refresh and then on “Upgrade”. This method provides a visual confirmation of package changes and is useful when you prefer GUI-based management.

As you can see, the upodate is in progress.

When prompted on the package configuration setup as shown below.

As you can see, the node has been updated 9.1.11.

Upgrade to v9.2.3

As mentioned earlier, there is a new version. To perform this upgrade, navigate to the Node, click on “Updates”, and click on Refresh and then on “Upgrade”.
