This Knowledgebase article provides information about performing a switchover during vMotion Operations.
Attempting to perform a switchover during active vMotion operations may result in errors during the vMotion. Although the switchover will complete, the vMotion operation may not complete.
Neverfail recommends that users not perform switchover operations while vMotion operations are running to prevent errors and allow the vMotion operation to properly complete. Once the vMotion operation is complete, switchover maybe safely initiated.
