reassign zfs pool lun

I have a branded zone txdjintra that utilizes a pool named Pool_djintra that is no longer required. There is a 150 Gig Lun assigned to the pool that I need to reassign to another branded zone txpsrsrv07 with a pool named Pool_txpsrsrv07 on the same sun blade. What is the process to do this?

+backup zone to be removed
+ destroy zone to be removed
+zpool add lun to zone that needs disk space
+??

I am very new to admin postion and appreciate any guidance in this.
Thanks and have a great day
