If It Ain't Broke, Should You Still Upgrade to Proxmox 9?
Every homelab eventually reaches the same moment. The system is stable, virtual machines are running smoothly, backups work, and nothing is broken. Then a new version of your virtualization platform appears, and the question pops up: should you upgrade, or just leave everything alone?
That exact dilemma sparked a discussion among Proxmox users running version 8 at home. One user summed up the feeling perfectly: if the current setup works fine, is there really any reason to go through the effort of upgrading to version 9?
The responses were interesting. The answer depends less on exciting new features and more on how people think about stability, security and long-term maintenance, and the community ended up splitting into a few very different camps.
The security crowd: upgrade before it's too late
One group didn't hesitate at all. For them, the biggest reason to upgrade was support and security updates, more than any new functionality. Several people pointed out that Proxmox 8.4 will eventually reach end-of-life, which means no more security patches after that point.
One commenter put it bluntly: upgrade before the current version reaches the end of its support window. Once updates stop, the system may still run, but it slowly becomes more vulnerable over time.
Another participant challenged the classic "don't fix what isn't broken" mindset. Administrators used to celebrate servers that ran for hundreds of days without rebooting, but today that can mean hundreds of days of unpatched software. From their perspective, staying current with updates is basic operational hygiene and no longer optional. For these users, whether to upgrade is settled, and the only question is when.
The pragmatists: upgrades are usually safe anyway
Another group had a more relaxed take. They didn't claim Proxmox 9 included any single "must-have" feature, but they pointed out something important about the platform's upgrade process: compared with many infrastructure systems, Proxmox upgrades tend to be relatively straightforward.
One experienced user explained that the upgrade path is well documented and supported by tools designed specifically for the transition. Running the provided upgrade scripts and following the official documentation usually results in a smooth process, as long as you've prepared backups first.
This view treats upgrades as routine maintenance more than risky operations. Instead of waiting for a big new feature, these users simply upgrade when it's convenient and supported, the infrastructure equivalent of keeping your operating system updated instead of skipping multiple generations.
The feature hunters: what's actually new in version 9?
Some users were curious about actual improvements. Even if the upgrade process is safe, people still want to know what they gain from moving to the new version.
One feature that caught attention involves container workflows. Proxmox 9 introduced the ability to import Docker images directly into LXC containers. That may sound small, but it solves a common annoyance. Many Proxmox users previously ran Docker inside a full virtual machine. The new approach lets administrators take Docker images and convert them into LXC containers directly, avoiding the overhead of running a separate VM just to host Docker.
It's not a perfect replacement for Docker yet, but it opens an interesting door to running prebuilt container images in Proxmox's native container environment. For homelab users who rely heavily on containers, that feature alone might make the upgrade worthwhile.
Storage improvements that matter to homelab users
ZFS improvements came up quickly as well. Proxmox relies heavily on ZFS for storage, and newer versions of the platform typically include updated ZFS releases with performance improvements and new capabilities.
One highly anticipated feature mentioned in the discussion was RAID-Z expansion. For years, expanding a RAID-Z pool required rebuilding the entire array. With newer ZFS versions, administrators can gradually expand a pool by adding disks.
In home lab environments, where storage upgrades often happen bit by bit instead of all at once, that can be extremely valuable. Instead of replacing an entire storage array, you can grow it over time, and that alone makes the upgrade appealing for people who rely on ZFS heavily.
The "wait for 9.1" philosophy
Despite the excitement around new features, some users still preferred patience. Their strategy is simple: wait for the first point release before upgrading.
Version 9.0 might introduce major changes, while a release like 9.1 often includes bug fixes, stability improvements and minor adjustments discovered after the initial launch. For administrators running production environments, even small home labs, waiting a little longer can feel like a safer path.
They trust the platform fine, and the wait is simply about letting the broader communi
