Before updating your company file to a new version of QuickBooks, consider giving your file a 'check-up' to reduce the possibility of errors occurring during the conversion process.
It is possible that your company data file already has damage in it but the damage is not visible because that particular area (record) is not touched. When you update your file, every area is touched and previously unknown data damage can become visible. Sometimes, this damage cannot be fixed in the updated file. It much easier to fix damage in your file before you update it. The probability of hidden damage increases with:
Note: For best results, refer to update QuickBooks to the latest release.
Note: If you use Add-on financial features such as Loan Manager, Business Planner, Cash Flow Projector, etc. use Backup and Restore to convert the Company file to new version of QuickBooks.
If you cannot find your data file in its original location, and if it is not in the specified folder, search your hard drive for *.qbw files and try to find it that way. Be sure to include hidden files and folders in your search criteria.
If you cannot locate your Add-on files see Restore other files not included with a restored company file backup
