Replacing Core Java with OAF pages

Hi all,

In order to future proof a customisation and web enable it, is there a roadmap that I could follow to migrate custom processes implemented in legacy core java forms to standard OAF? My orgainistaion is moving to a shared service and on the shared service platform, enhancements are delivered via standard functionality rather than customisations and OAF rather than core Java is the preferred technology. I woild appreciate any advice as to how to reduce core Java abd replace with OAF across modules like Inventory and Purchasing
