Role Expert and transporting of roles

Dear all,

With a typical ECC landscape consisting DEV, QAS and PRD, roles are created in DEV using PFCG and then transported from DEV using the truck icon in PFCG.

With Access Controls - Role Expert installed and connected to my ECC DEV system, I create roles on DEV.

What do you suggest to do next:

1) transport roles from DEV using PFCG

or

2) create the same roles on QAS and PRD via a Connector on the Landscape

3) install a GRC Role Expert box for each system (QAS and PRD) and use the Role Import function to upload role files previously downloaded from DEV.

Any help greatly appreciated.

Thanks,

Babak
