Leading UK-Based Global Bank
Teradata's end-of-life put vast data volumes and critical business logic at risk, with zero room for disruption to daily operations.
The context
A UK-based global bank serving millions of customers needed to migrate off Teradata ahead of its end-of-life deadline. Critical processes relied on Teradata BTEQ scripts, stored procedures and SAS-based workflows, making the transition highly complex, and any delay meant operational risk and rising cost.
