Major UK card issuer
Major card portfolio migration
Move a card portfolio while maintaining control across configuration, data, testing, cutover and live-service readiness.
Dependencies crossed issuer and processor boundaries and continued beyond the migration event into live service.
The work connected configuration, mapped data, test evidence, cutover decisions and live-service ownership through a controlled delivery path.
Doxa supported configuration assurance, data verification and mapping, UAT, incident triage, gap resolution and specialist continuity into warranty.
Go-live and warranty activity were supported through clearer ownership, visible evidence and retained specialist continuity.
