Besure to check that the copy of the Ledger you are restoring are not missing batches from the sub ledger that you have retrieved. You will not be able to re-retrieve the sub ledger batches to the Ledger again. By either moving the old Ledger data to a new folder or renaming the ledger data, you can always check it the restored ledger to theold ledger. Also if you do rename or copy the data, be sure to go in to the data, change the company name to "Old Data" and change the screen colour. You do not want to be posting in the old copy by mistake!
