A colleague is demonstrating the VMAX virtual LUN migration feature. They configure four
test devices to move from FC RAID 5 volumes to SATA RAID 6 volumes and start the
migration. The colleague reports the LUN migration moves very slowly and appears to stop
during peak processing times. What is the likely cause of the issue?

A.
The VMAX is reaching system write pending limits.

B.
FAST VP is interfering with virtual LUN migration processes.

C.
They are attempting to migrate too many volumes at once.

D.
The target volumes are the same size as the source volumes.
