Conversion of Service contract invoice

HI,

We are changing existing ledger and OU (Local COA) to new OU & Ledger ~(Global COA).

We have to transfer all the open transaction during go live to new ledger.

for Service contract invoices where revenue recognition rule is defined how to transfer those pending revenue recognition lines to new OU. Is it needs to be manually enter in GL every month or can we do some other automated way ?

Thanks,
