I created this to allow me to migrate from different storage backends for a given project. The process would be:
- Create a new PVC using the preferred storage backend
- Shutdown app (scale replicas to zero)
- Run sync process job
- Edit Pod specs to use new PVC
- Scale app back up
oc process -f job-template.yaml SOURCE_PVC=sourcepvc DEST_PVC=destpvc | oc create -f -
