There's no easy way to convert business accounts to person accounts, but it can be done.
To complete the conversion, you'll need to export a file containing the accounts and contacts to be converted, manually alter some data, and then import the it back into Salesforce. You can also convert person account to business accounts using a similar procedure.
Tip We strongly recommend testing your conversion in a sandbox before importing
altered data into your production organization. For more information on sandboxes, visit Sandbox Overview in the Salesforce online help.
