Convert your QuickBooks file
QuickBooks 2008 can directly upgrade company files only from QuickBooks 2004 or later. If your company file was created in QuickBooks 2003 or older, please refer below.
To work around this issue, you can download and use the QuickBooks Conversion Kit. Use of this kit is free. For more details, see see Upgrading from QuickBooks 2003 or older.
