Clustered Data ONTAP (now known as NetApp ONTAP) is a clustered file system that leverages virtualized storage containers known as Storage Virtual Machines (SVMs) that act as “blades” to create a secure, multi-tenant environment with a unified namespace.
These SVMs own objects such as network interfaces and Flexible Volumes (FlexVols) and act as their own segmented storage systems on shared hardware. In previous releases, the volumes were dedicated to the SVMs and could not be easily moved to another SVM in the cluster. You had to SnapMirror the volume over to the new SVM or copy the data. This process was time consuming and inefficient, so customers, for years, have asked for the ability to easily migrate volumes between SVMs.
In the 8.3.2 release, this functionality was added in limited fashion, for use with the new Copy-Free Transition feature. The volumes could only be migrated if they were…
