Trustmark, a large diversified financial institution based in Mississippi, implemented ARP/SMS from Fiserv (Account Reconciliation Package/Service Management System) in May 2005. The financial institution upgraded to 8.0, but hadn't upgraded since then. When the time approached to sunset the 8.0 version, Trustmark considered its options for upgrading to the new 10.0 version with the least amount of disruption.
Trustmark had implemented a considerable amount of customization over the years, which would take longer to upgrade. However, when Trustmark learned Fiserv offered an implementation service that would take the existing code, with all its customizations, and upgrade it to 10.0, the financial institution jumped at the chance to use this service.
