Ferd, the best way to operate the current FOM depends if you knew where the info was previously found (eg chapter) or if you like the index. If you knew where it was originally, just go to the old NW FOM pages and see what the reference says on the right hand side. If it says NW...than that reference applies, if it says DF, the DL FOM reference applies. If you can not find it in the old chapter..look in the index and go to that reference. You also use the exceptions pages to cross check the validity.
There still will be unresolved issues at SOC and after.
