PhysX 4.0, conversion from PxRigidDynamic to PxRigidStatic and vice versa

I’m implementing a simple physics simulator and I wanted to know if it’s possible to convert PxRigidDynamic to PxRigidStatic.

I think you can’t.
Release your static actor and create a dynamic one, and vice versa.
That’s what I’m doing.
