A deep look at how a full portal rebuild and phased data migration eliminated the single biggest source of client complaints.
01 Overview
This case study walks through how we approached migrating a decade of financial account history with zero tolerance for discrepancy, while shipping a portal fast enough to stop the bleeding on client complaints.
02 The Challenge
BrightLedger's legacy portal was the single largest source of client support tickets, and any migration approach that risked even minor data discrepancies was a non-starter for a financial services company.
03 The Solution
We ran a shadow migration in parallel with the live legacy system for six weeks, reconciling every account automatically before a single client was cut over, then migrated clients in small batches with rollback points at each stage.
