Rewrite OneWorld AR to World AR...

Hello, We are a co-existence customer. We use OneWorld Xe for our Accounts Receivable module only, Order management, pricing, inventory and other pieces are all on World A73cum8(with a few programs supporting co-existence in higher cum level). Now Xe is no longer supported next year, we are looking for ways to take us out of the co-existence situation. I heard someone talking about rewrite the functions in OneWorld AR back to World AR. Is this possible? Or from cost/benefit perspective, it's a bad option? Thanks in advance.

We have similiar case here. We only run AR in OneWorld ERP8.0 and run the rest of the world in World A73cum12. The way we plan is moving forward. Move all distribution, manufacturing, finance into Oneworld. In this way we can get better and more function out of the package.
