Core Banking Data Centre Migration

Migrating a tier-1 microfinance bank’s core banking platform to a redundant dual-site architecture, with zero unplanned downtime during cutover.

The Challenge

A single-site data centre outgrowing its own transaction volume.

The bank’s core banking platform ran from a single data centre with no redundant failover site — a growing risk as transaction volume increased and regulatory expectations around business continuity tightened. A single power or hardware failure risked taking core banking services offline entirely, with no documented recovery path.

Compounding the risk, the existing server environment was aging, undocumented in parts, and sized for transaction volumes the bank had already outgrown two years prior.

The Solution

A dual-site architecture with a tested, phased cutover.

Rather than a single high-stakes migration weekend, the engagement was sequenced to de-risk the cutover at every stage.

Infrastructure audit

Full assessment of the existing server estate, dependencies, and undocumented configurations.

Dual-site design

Redundant data centre architecture with automated failover between primary and secondary sites.

Phased server migration

Core banking workloads migrated in stages, validated at each step before proceeding.

Failover testing

Simulated failover events tested and timed before go-live, not left to chance.

Documentation handover

Full as-built documentation delivered so the bank’s internal team could operate the new environment.

Post-migration monitoring

24/7 monitoring during the stabilization period following cutover.

The Results

What changed after go-live.
