It is important to check that the balance on all customers accounts from the aged listing agrees to the control account in the old system, in both local and overseas currency. The balance in the general ledger (of all customer balances) would normally be entered as a manual journal, but the amount of this journal should agree to the amount as per the customer listing. Of course balances entered in different currencies will have a different local value depending upon the rate at which they were entered.
There is a facility to value all the currency balances in local currency looking at the rate at which each transaction was entered. This is the script Z_CurrencyDebtorBalances.php. A similar facility is available for suppliers balances. A double check should be done account by account before going live. Once all customer accounts are reconciled and entered (and double checked).
The General Ledger interface should be re-enabled from the Company preferences screen (System Setup Tab). The system will then maintain the control account in the general ledger which should always agree to the list of balances.
