+Cloning operations between different volume modes are supported, such as cloning from a persistent volume (PV) with `volumeMode: Block` to a PV with `volumeMode: Filesystem`.

+
+[TIP]
+====
+When you enable preallocation globally, or for a single data volume, the Containerized Data Importer (CDI) preallocates disk space during cloning. Preallocation enhances write performance.
