Optimizing physical adapters

Imagine 3 VMware ESXi 5.5 servers members of a vSphere infrastructure.

Each server is confngured with:

• 1 physical adapter associated with FT and Management Network
• 1 physical adapter associated with Vmotion
• 1 physical adapter associated with iSCSI (on a dedicated physical switch)
• 2 physical adapters associated with production VM port groups

I need to reduce che number of physical interfaces.

Can I associate Vmotion, FT and management Network to the same physical adapter?

Can I associate all the production VM port gropus to the same physical adapter without recreating the port groups to be moved?

Is there any documentation about the best way to associate VMkernel ports and port goups to physical adapters?
