You can use QIF Export to export all the exportable account and list information in a specific data file, and then use QIF Import to import all the importable account and list information into a new data file. This process imports all account information from one Quicken data file to another at one time.
QIF import is available only for asset and liability accounts which include house, vehicle and cash accounts. If you have purchased Quicken Premier Home & Business, you can use QIF to import transactions into accounts payable accounts and invoice accounts as well. QIF import is also available for any exported list, but the file you want to import the list into must already include a valid account.
QIF import is not available for checking, credit card, savings, 401(k), or any other brokerage accounts. To import transactions into these types of accounts, refer to the article Changing your method of download from QIF import to OFX.
The following items cannot be moved to a new data file with the import and export procedures and must be entered manually.
Note: Account balances may not be correct after undergoing the export/import process. If you created a new copy of your data using the Year-End Copy command, Quicken removes reconciled transactions from the newly created data file, but does not remove cleared transactions outside of the date range you specified. This can mean that a transfer transaction between two accounts can still appear in one account but not the other. When you use the import/export commands to move this account information to a new data file, Quicken automatically rebuilds the previously removed reconciled transfer transactions back into the second account, which can lead to incorrect account balances.
