Migration from Property Manager to Fusion Lease Accounting

Summary:

I have to migrate leases from property manager to fusion lease accounting. By following the approach suggested by the oracle, we migrate the leases with closing net-ROU of leases at the time of migration. But upon termination only accumulated depreciation which have been calculated after the migration will be accounted. This approach finds correct figure for gain or loss at the time of termination. But pre-migration balance of accumulated depreciation will remain in the GL. How we have to settle it?

I have tried by giving the balance for Gross-ROU of leases and accumulated depreciation, but the system has not picked these balances and while uploading lease through FBDI rejected by the system with the error "You must enter the finance ROU balance value for the migrated lease." So, we entered the balances for closing net-ROU along with the Gross-ROU and accumulated depreciation. Then the system processed and calculated only on the basis of closing Net-ROU and ignored the Gross-ROU and accumulated depreciation.
