We're new to the CX 6200M, coming from the 2930M switches with the separate two port stacking module.

Does anyone know specifically how the stacking bandwidth / throughput between two 2930M switches and two 6200M switches are different?

10Gig on the CX 6200M between two switches seems limiting (maybe it was the same on the 2930M?) 

Is there a way to aggregate two stacking bandwidth between  6200Ms by using additional 10 GIG ports in a LAG?

Hi, the Aruba 2930M provides - through its dedicated Stacking Module - a stack port throughput up to 25 Gbps and a stack module throughput (two interfaces) up to 50 Gbps.

Speaking about Aruba CX 6200M deployed in VSF the "stacking" throughput is ruled by aggregated throughput of involved interfaces (you can aggregate them for sure), under the basic rule of "the more the better" but there are other reasons to select the most appropriate bandwidth (thus interfaces) for the VSF Links between VSF Members.

Have a look at latest ArubaOS-CX VSF guides here (AOS-CX 10.12) and here (AOS-CX 10.13) to understand the VSF and how to correctly deploy it (best practices).
