Western VistaWestern Vista, a credit union in the US state of Wyoming, has converted from its legacy tech to a new core processing platform, Keystone. The system is supplied by domestic vendor Corelation.

Meanwhile, the San Francisco-based vendor has also signed five new deals to implement its flagship core system.

The new takers are: AEA Federal Credit Union in Arizona, Centris Federal Credit Union in Nebraska, Marshland Credit Union in Georgia, Del Norte Credit Union in New Mexico and SIU Credit Union in Illinois.

Corelation now has a customer base of around 75 credit unions across the US, mainly in the lower-tier space. The largest Keystone users are Desert Schools Federal Credit Union ($3.8 billion in assets) and Pennsylvania State Employees Credit Union ($5 billion in assets).
