Integrating Subscription Nodes into Existing Non-Subscription Cluster

[zero-skill]

Hi everyone, newbie here, I currently have an existing Proxmox cluster running on non-subscription nodes, and I’ve recently deployed two additional Proxmox nodes with valid subscriptions; I’m considering joining these subscribed nodes into the existing cluster and would like to ask if it is technically supported to mix subscribed and non-subscribed nodes within the same cluster, whether there are any limitations or risks (especially regarding repository differences like enterprise vs no-subscription), and from a best practice perspective, would it be better to integrate them into one cluster or keep the subscribed and non-subscribed environments separate? Thanks in advance for any guidance.

Thank you!

Hi @zero-skill, welcome to the forum.

This has been covered a few times, for example: https://forum.proxmox.com/threads/j...t-is-licensed-what-happens.108160/post-465204

I believe this is the most accurate answer.
Please refer to the staff comment and the subscription agreement linked from it:

Hi,

if you add a node that has no subscription to a cluster that otherwise does, the node will work just fine. Depending on how you configured the repositories on you subscribed nodes you might have to deal with some version mismatch issues, but nothing is currently known that should cause problems.

Be aware though that the subscription agreement clearly states that the subscription level defaults to the level of the node with the lowest level in the cluster. Hence, if a node does not have a subscription, the entire cluster will be handled at the no subscription level.

In short, integrating the clusters offers little practical benefit, because the subscription you purchased would effectively no longer be usable for that cluster.
