It all depends on the overall architecture of the system. One just cannot held disk for at fault, you have to look from all aspects, what is the memory? what kind of disk were you using? did you correctly set the queue_depth value on the disk? how is the disk coming to system (NPIV or vscsi). Also check the iostat command.

During the migration, one might see processing delay or performance degration, but not in all cases.

Need more info to help you.
