CRD Migrations - conversion webhooks

[theodor-franke]

Has anyone experience with migrating a CRD to a newer version?
I want to alter some fields in my CRD that is already deployed to production. The K8s docs tell me to create a conversion webhook and have the two versions of the CRD installed in the cluster for a period of time. I understand this approach, but I do not see any documentation for this in this project or the Fabric8 client. I am auto‑generating the CRDs.

I think this is a common problem. How did you solve this?

Hi @theodor-franke , we have a dedicated separate framework for that in place:

I beleive it is quite common if you have to migrate.
