transfer of AUC?

HI gurus,

There is a scenario which has to be solved,

I am transferring some costs from one WBS to another whose budget is maintained by IM program, and it has been periodically settled to an AUC , now the business wants to transfer the ongoing project to the new company code so, what we proposed was using a journal entry and dummy budget we can transfer the line items to the new WBS, but the problem is the existing settled costs which are already sitting in the AUC, how can this AUC be linked with the new WBS in the new company code,

As the AUC is automatically generated by the link between IM & PS by Im profile, as we are using the same IM program and profile for the new WBS, is it possible that the AUC will be automatically transferred to the new WBS?

Immediate help would be really appreciated.

thanx
