Receipt reversal in secondary ledger - original data exist in prevoius SOB

In R11i we have 2 SOB for accrual and cash, any only some specific transactions from the primary SOB were created in cash SOB (receipts to view the respendable revenue).

Now we have migrated to R12 and configured the previous cash SOB as a secondary ledger to the primary accrual ledger. When testing to reverse a receipt which was from the pre-migrated data the reversal is not recorded in the secondary ledger as the original data was not recorded there.

Is there any standard way to fix this reversal in the secondary ledger.

TIA,
