Cutover after a VNX File with RecoverPoint SE Failover.

Hello Community,  I am looking a document that explain how to do a cutover  after a Failover from VNX File with RecoverPoint SE.   in other words I want to convert the DR Site  on Production Site.

I did the Failover  on my environment  (VNX 5200 File  replicating to DR Site with RecoverPoint SE)  without problem.  and want to do my DR Site on Production Site.

Any Help will be appreciate.
