I did a quick search, and it sounds like if you can do the data migration, that would be the “safer” route to take.  Might want to review this based on what flavor of ontap you are running.

Subject: SnapDrive shrink lun

Happy New Year Toasters!

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.
Kevin
