In assign vertex colors panel you can choose what channel you want to bake to. If it's an already baked channel you can use the map channels info, where you can copy paste channels data.

you can also copy and paste Vertex colour information to Vertex Alpha using the Tools>ChannelInfo rollout. Copy VC to :Alpha

or

First extract VC to a texture using R2T and a vertex colour material. Then using Vertex paint modifer, as the baked texture as your diffuse, bake this to the desired channel.

Alternatively try this neat cuda accelerated AO -> vertex channels baker, it does regular vertex color or vertex alpha and it is close to instantaneous on most meshes.

(that is ofcourse if ao is what you are wanting to bake)

Your info. helped me a lot. I wanted to convert vertex alpha to vertex color and I did it with copy/paste in Tools>ChannelInfo rollout. After that I just had to change colors in vertex paint mod.  (adjust color tab)(click on "condence to single layer" button before use)
