Is there any mechanism to stage upgrades in a cluster? Namely, for instance with 11 nodes, upgrading them gradually over the course of several days, maybe in groups of 3 sounds like a good strategy, but how to know when it's safe and when not? Or is it guaranteed to be always safe within a major version?

Secondly, if there is any issue found, how to downgrade or reinstall the affected node to hold off before e.g. resolving the issue?

Currently, when installing from ISO, there is some relatively historical version installed and running upgrade simply brings it to the most recent, so there is no stages like with a kernel, correct?

Would it be easy to e.g. dual-boot 2 separate versions altogether?

Is anyone aware how white-labelling the UI goes as far as Proxmox stack is concerned?

Clients would like to see their own logo on their nodes in the UI as they resell. We thought it might be possible as part of stock configuration, but did not find anything to that effect. Technically, exchanging the .png in the assets directory is a non-issue, but how common is this? Also probably worth mentioning we provide managed service, so we can keep the logos in sync.

Anyone had any technical or other issues or in general has experience with white-labelling Proxmox, including e.g. CSS theming?
