How to update COA on Converted Purchase Orders in bulk

Summary:

The converted POs and Invoices had an expenditure Org "XXXXXX" which was mapped to a cost center YYY. the cost center was disabled post conversion. However, the PO and invoice distribution needs to update the COA segments per the latest SLA rules. Users are able to manually "rebuild accounts" action but there are thousands of PO/invoices which need this change and therefore a quicker mass method is needed. Also, for POs which are closed for invoicing, the rebuild account action does not work.
