Keeping a legacy LMS alive: AS/400, RPG & compliance
How Adroitent took end-to-end ownership of maintaining and modernizing a decades-old legal management system across IBM AS/400 (RPG, LANSA), PowerBuilder and Java — while delivering a US 1099 tax-compliance overhaul.
The inflection pointA complex, multi-layered legacy estate
The customer's core application, LMS, spans multiple layers and versions — built on IBM AS/400 with RPG and LANSA for back-end processing and PowerBuilder and Java for the front end — and needed ongoing maintenance and modernization across LMS 4, LMS 5 and LMS Plus, plus a major US 1099 tax-reporting overhaul.
- Maintaining LMS 4, a legacy RPG/LANSA system
- Supporting feature enhancements across LMS 4, LMS 5 and LMS Plus
- Integrating compliance-driven changes within short timelines
- Managing multi-channel communication and ticket lifecycle via Zendesk & Jira
- Navigating VPN access and security issues while collaborating remotely
Keep decades-old software stable, supported and compliant.
