Whats the best practice of bringing the CIP cost from 11i to R12 instance

Hello,

My customer is doing reimplementation R12.

They have expenses and CIP cost in R11.5.10 instance.

How should we bring these transactions to R12 instance.

Will it be costed and accounted, then in that case how project to GL will balance .

Should we bring them as uncosted then how to process the transactions in the respective period.

For asset generation, it seraches for the expenses to be accounted and transfered to GL.

In this case how to handle the capital expenses as they are already accounted in 11.5.10.

Regards,

Rajiv
