Government Customs Portal – Liferay Migration & Clustering

The Challenge

Migrating a mission-critical portal in a strict security environment while ensuring zero data loss and achieving high availability through clustering.

The Strategy

Implemented a two-node Liferay DXP 7.4 cluster behind a Layer 7 Load Balancer and executed a rigorous two-stage database migration protocol.

Implementation Details

• Migration: Led the version upgrade from 7.2 to 7.4 including database schema reconciliation.
• Clustering: Designed and maintained a highly available Liferay setup for scalability.
• Optimization: Oversaw infrastructure provisioning and performance tuning during cutover.
• Collaboration: Worked with QA and dev teams to ensure minimal downtime.
