Quick question for the group, we have a lun that was increased from about 3TB to 7TB.  We now would like to shrink it down.  My understanding is that I can only cut it by half due to a limitation of the OS (Win2008R2).  My other concern is data corruption, etc.  I have the option of adding a new lun and migrating data.  Any recommendations from experience?

Thank you.
