can you convert points into pro points?

Does anyone know if and how can you convert the old points to the pro points?

we've got the old points weight watchers cookery books and wondered if it's possible to convert them?

Thanks in advance =)

I still use some of my old ww cookbooks, as far as I know there's no direct way to convert points to pp, but it's easy and quick enough to work out the points line by line and write them up in pencil on the recipe. You could sit down and write up all your faves in an hour or so, max !
