How many LUN migrations can run simultaneouosly - CX4-480C

Hi All;

I am having some trouble finding a best practice for how many migrations can occur simultaneously, I will frame my question by showing what I am planning to do:

I am moving 8 1TB LUNS from a storage pool to 8 1TB LUNS in a Raid Group.  The 8 LUNS are evenly spread (4 each) across the SP's.

Is it possible to run all 8 at once (and set the priority to low) or is there a best practice?  The array will not be busy when I am doing this on Saturday, will be very quiet actually.

Thanks for your replies in advance.
