The following error is reported when attempting to upload a BAR file using the BlackBerry® World™ Vendor Portal.
Package ID already in use
An BAR file with the same package name has already been uploaded using a different vendor account.
If you need to upload multiple versions of your application to different vendor accounts, ensure that you have a unique package name for each vendor account. Keep the package name for each vendor account consistent to prevent issues for users upgrading to newer versions of your application.
Modifying the package name for an existing application will prevent users from upgrading to your new release. If a user attempts to install the new version with the modifed package name the application will appear as a second icon on their device and the upgraded application will not have access to the previous application's saved data.
