If you open a company that was created in an earlier version of Microsoft Office Accounting 2008, you must upgrade your data file so that the current version of Office Accounting 2008 can work with it.
To start the upgrade process, click OK. Accounting 2008 creates a backup file and then proceeds to upgrade your data in the Backup dialog box. We suggest that you save your file in the following location:
Windows Vista drive:\Users\user\Documents\Small Business Accounting\Backups
Windows XP drive:\Documents and Settings\user\My Documents\Small Business Accounting\Backups
