Where can I find latest documents related to ASCP and how to implement it?

I have been using MRP for past 10 years, by growing number of planned parts, we will reach to 2G memory limit for 32 bit MRP in the next few months the only choice that I found in metalink is to go to 64 bit ASCP since we've un-peg all parts already and even  sometimes unplanned some parts, now we need latest documents about how to setup ASCP and specially how to switch and migrate from 32 bit MRP to 64 bit ASCP related to our application version which is 11.5.10.2.I'll be glad if you can  send me some link.
