2-node 6.5 SP6 cluster attached on a EMC CX400 with PowerPath
DATA (old) pool build from mixed types LUNS
DATA2 (new) pool build from one LUN

I have to migrate the files from the Volume DATA to the new Volume DATA2
at the same server (about 400GB). Because of the huge amount of data, a
copy using the migration tool takes about 16 hours. Is there a faster way
(snapshot, mirror etc) to bring the data to the new volume using the whole
bandwidth of the FC?
