Move between Kustomization and HelmRelease

[Legion2]

Currently I manage my manifests with kustomize and use a Kustomization to reconcile them in the cluster. Now I want to move some of the resources to a helm template and then reconcile them with HelmRelease. For the migration step the manifests are not changed, only how they are reconciled.

Now the Problem is, that prune is set to true in the Kustomization. So during migration, kustomize-controller will delete the resources while helm-controller reconciles them. For most resources this is not a problem, but for stateful resources, such as PV and PVC, the persistent data would be lost. So my question is how would I move manifests from Kustomization to HelmRelease?

One solution I can think of is to disable the pruning for the PV and PVC before moving them. But this would still cause a minor disruption of the service, because all other resources are recreated.
