A donor has the ability to enter a recurring gift through the form, event or directly on their contact record. An organization migrating off of Sphere might wish to export the credit card information for these recurring gifts so that they can be entered into the new processor without disrupting the gift cycle.
Credit card numbers, aside from the 4 digit credit card mask, are not stored in Sphere. They are not available for review or for exporting. This is to ensure Sphere remains PCI compliant.
Rather, your organization is able to run a report on outstanding recurring gifts to review the contact information for those donors who still have recurring gifts. Those donors can then be contacted in bulk and requested to re-enter their payments in your organization's new processor interface.
CyberSource is the payment processor used for Sphere. If you have further questions about this processor, you may contact CyberSource.
