VC non-provisioned to pre-provisioned while running

Hi all,

we have a VC with 6 Members, currently non-provisioned.

Customer has 3 more VC's, all pre-provisioned and asked if we could change the non-provisioned to pre-provisioned to have "one config" - but without taking the VC out of Service.

Is this safe? Can i just set the chassis to pre-provisioned with the current member-ID's without risking the VC to renumber or do other "silly" Stuff?
