What are the steps to migrate RBD images from one ceph pool to another?

Environment

• Red Hat Ceph Enterprise 1.2.3

Issue

• Is it possible to migrate RBD images from a Ceph pool to another? If so, how?

• How to migrate existing RBD images from one pool to another, in an Ceph cluster?

Resolution

• In order to export an RBD image from an existing pool to another one, use:

# rbd export [image-name] [dest-path]

• A similar method, but to import from another pool into an existing pool:

# rbd import [path] [dest-image]
