Vendor Name Change - PeopleSoft Purchase Orders

Hi,

One of our vendors changed its name and Tax ID recently, and there are hundreds of purchase orders for this vendor in our system (PeopleSoft Financials).  All these purchase orders have contracts, vouchers, and receipts associated with them in PeopleSoft.

I am researching an effective way to replace the old vendor name with the new vendor name for the existing PeopleSoft Purchase Orders.

I would appreciate it a lot if you could recommend a solution.
