MPIO features/changes needed for third party DSM on window 2012 server edition

Hi There,

Where i can get information about new feature/changes about microsoft mulitpath solution(MPIO) for SAN devices.

I am looking for any new feature/changes that third party DSM vendors need to make to make sure their solution works well on windows 2012  server edition.

We have DSM driver which was supported for Win-2008 R2 , can we use the same driver (assuming we are not adding new feature) for testing against windows 2012 server edition

thanks,

Sidharth
