[CA11] Upgrading from e series to Axiom Pro

I am planning to upgrade my existing dual screen e series system to the Axiom Pro. Replacing an e125 and an e127 with 2 new Axiom Pro 12 RVX units. Can I simply install the new Axiom units using the e125/127 cables already in place? I understand that a new cable for the RVX Transducer and any other other changes must be made. My power and network cables are already in place and it would save me a great deal of work not having to cut them out. This system is being installed on a 31' SAFE Boat full cabin patrol boat.

Thank you
