Definitly, we need multi currency with the migration tool. All transactions in summary or in detailed if possible should be imported in originating currency.

Also in BC, if the exchange rates are already imported, the migration should consider importing the exchange rate of the transaction in GP.

Sometimes a transaction use a different exchange rate in a same day, in the migration tool, it would be really great to get the same historical information from GP to BC.

Please add the originating currency in General Ledger entries in BC, it is not available right now in BC.
