Running AR and IEX in parrallel

Hi all,

I have an unusual requirement from a client where they wish to continue to run AR dunning letters whilst also starting to use IEX functionality. By this I mean that they will remove letter sets against particular profiles and for those profiles collect them in IEX by using unique views.

On the previous Advanced Collections implementations I have done this has always been a case of moving all debt from AR collections to IEX collections, this will eventually become the case at my client but they would like to do this in stages... Whilst I am aware this is possible, just thought I would ask if anyone else has ever had to do this and if they could kindly share any issues/experiences they had whilst doing this?
