@ykakarap Looks good. I assume it's safe in upgrade scenarios as we re-create the Certificates anyway. Should we document this in the v1alpha4->v1beta1 migration guide?

@sbueringer I just did a local test and I was able to continue creating clusters after upgrading from v1alpha4->v1beta1. Are there any more elaborate checks I can perform?

I don't think so. I think it's safe, just wanted to mention it (in case someone has more insight and sees a problem). Let's trigger the update e2e test as well:
/test pull-cluster-api-full-e2e-main

P.S. Here is a log with the certificate re-creation during clusterctl upgrade I was referring to: https://storage.googleapis.com/kubernetes-jenkins/logs/periodic-cluster-api-e2e-main/1445386455730884608/artifacts/clusters/clusterctl-upgrade-ogusut/clusterctl-upgrade.log
