Transfering contacts from one module to another

Transfering contacts from one module to another

Hi,

I have created a custom module to managed a list of participants (which is different from our accounts / contacts (clients) list)
This custom module is called Consos.
These contacts are more like our 'raw material' (please don't it wrong - I don't like saying this but it is a way to explain)

The consos contacts until now where managed in the same base as our clients base under the module contacts.
(which wasn't really adequate and this is why we created a dedicated module)

Now I have a problem : I would like to transfer all the contacts that were initially mixed with my clients contacts into my new custom module.

How should I do that ?

Thanks in advance
Here after a screen shot.
