Is it possible to do it?
Sure, it is possible.
The first option you may try is using the VNX tools as described here https://www.dell.com/community/VNX/How-to-create-a-clone-of-an-existing-LUN-in-a-storagepool/td-p/69...Opens a new window.
The second option is connecting both LUNs to the same server and using disk cloning utility of your choice. CloneZilla is a good option to start with https://clonezilla.org/downloads.php/Opens a new window.
