Re-inputting sales data for previous year
Hi, I have inputted the sales data in year 1 and year 2. For year 1, it is done by way of general journals, and year 2, inputted by filling in the information in "create invoice". Now I would like to re-enter the sales data by inputting information in "create invoice" for year 1, so that I can have my ageing ledger and customer ledger etc for both year 1 and 2. Is there any method, I can keep a backup data for my previous year 1 sales data somewhere, and just in case if I get anything wrong during the re-inputting data process, i can retrieve the back up. Or is there any suggestions for such action. Thanks
