What are the options for changing "allocation owner"?

FLARE 30, .517 patch.  Working with pool LUNs for the first time.  According to some other posts:

"Allocation owner of a pool LUN is the SP that owns and maintains the metadata for that LUN. It is not advised to trespass the LUNs to an SP that is not the allocation owner. This introduces lag.

The SP that provides the best performance for the pool LUN. The allocation owner SP is set by the system to match the default SP owner when you create the LUN. You cannot change the allocation owner after the LUN is created. If you change the default owner for the LUN, the software will display a warning that a performance penalty will occur if you continue."

So, on our CX3-80 with FLARE 26, you could always move LUNs around to balance the SPs by changing the default owner and trespassing.  It appears that with a pool LUN this is not as simple. 

What are the options/best approach to accomplish this?  LUN migrator?

Thanks,
