I was testing kube-prometheus-metrics migration and the new install happened to use a different AD. Consequently, the migrate pod was unable to start because it could not mount 2 PVCs that were on different ADs. We need to document an alternative solution, which would to be mount the pod with a single PVC, copy the data to a local host, mount a second pod with the new PVC, and copy the data from the host to the new PVC. Use kubectl cp.
