Hi very detailed article. thank for that. Our usecase is little different. Have RWX and Retain attributes We are using efs-provisioner and wanted to migrate to AWS CSI EFS Driver. We added addon and defined new Storage class, PVC. But PVC is in pending state not bound with PV. Becase I have used old efs-id in the new Storage Class. Looking for a solution to migrate data from existing PV(created by efs-provisioenr) to new PV(Created by AWS CSI Driver). Can I use new efs-id in new storage class which helps PVC to PV bound and do a data copy? Can I use Rsync or pv-migrate tool to do data copy? Any other solution rather than deleting PVC,PV? For migration it seems I have to unbound from existing POD(Deployment) and mount to a new POD which also has new PV mounted? My intention is: Minimize down time, Work time, faster data copy.
