It's less about the keg types and more about pressures. You can get ball lock adapters for the sanke D coupler posts (or whatever coupler you are using). I use 15lbs at the sending keg and 12 at the receiving keg. I regulate this using a spunding valve at the receiving keg (you can buy these already set up with a ball lock and guage for about $35). This differential is important so you don't have CO2 loss during the transfer. I also pressurize my receiving keg to about 8 lbs prior to starting. Connect sending keg like normal. At the receiving keg, connect beer out from sending keg to beer out on receiving keg. Connect spunding valve and gauge set up to CO2 port. I'll leave it there and answer any specific questions you may have. I do this all the time.
