Enterprise Intranet: On-Premises Liferay DXP Migration

Objective & Constraints

Navigating strict on-premises infrastructure migration constraints, the Authority faced a critical roadblock: a vendor bug in standard upgrade scripts regarding the ar_AE (Arabic) locale. This defect threatened to corrupt the database schema of the entire Enterprise Intranet, risking data sovereignty breaches.

Strategic Implementation

Engineered a Parallel-Environment Migration Pattern on bare-metal VMs to ensure a fail-safe transition. By leveraging CI/CD Pipeline Automation, I enforced Infrastructure Parity across all environments and secured a vendor-validated fix for the locale-specific schema transformation.

Protocol Execution

• Automated Infrastructure Parity: Leveraged modular GitLab CI/CD pipelines to guarantee absolute environment consistency across isolated Dev, UAT, and Production on-premises servers.
• DevSecOps Hardening: Implemented Zero Trust Security protocols and air-gapped network isolation, integrating SonarQube to scan custom modules for vulnerabilities before deployment.
• Strategic Vendor Collaboration: Diagnosed and escalated a critical product bug in the Liferay upgrade tool, securing a verified resolution that preserved 100% of localized Arabic metadata.
• Real-Time Telemetry: Established advanced observability using Prometheus and Grafana to monitor JVM heap and upgrade telemetry, ensuring a flawless 30-minute production cutover.

Professional Reflection

"This project demonstrated that an Architect must be as skilled in technical communication and vendor negotiation as they are in systems design. Working without the 'infinite' resources of the cloud breed a discipline in resource allocation and deployment timing that is essential for high-security government environments."
