Upgrade guidance from older kube-prometheus?

[Ghazgkull]

Is there any guidance available that can help me navigate the upgrade process from kube-prometheus 0.4 to 0.7?

For background, I've inherited ownership of a kube-prometheus deployment which is currently on version 0.4. After upgrading Kubernetes (EKS) from 1.19 to 1.20 yesterday, our AlertManager has started firing constant alerts about not being able to find "all other members of the cluster". Looking at the K8s compatibility matrix for kube-prometheus, I see that 1.20 isn't supported in our ancient version so I'm guessing we just need to upgrade. I know next to nothing about kube-prometheus and I haven't found any documentation on upgrading except for the 0.7 to 0.8 upgrade, which looks like a major undertaking.

@Ghazgkull : sorry, not an answer but I have exact same issue with an older highly customised my.jsonnet file which has the v0.6 style which seems to have changed pretty much completely going to v0.7 style but I can't find any guidance at all. Did you get anywhere with this?

From commit histories, @kakkoyun, @paulfantom, @lilic seem to have been involved at least in part in the v0.6->v0.7 changes. Any chance y'all could give @Ghazgkull and I a steer on this - migration-guide specifically suggests posting here for assistance, but sadly there's been no reply for a month? Any help would be really appreciated by me :-)

I ended up using this opportunity to finally get off this Jsonnet-based project and moved to the Helm-based kube-promtheus-stack
