Modernization Strategies

Choose Your Path to Modern

We help you select the right modernization approach for each application

Rehost (Lift & Shift)

Move applications to modern infrastructure with minimal changes for quick wins and cost savings.

Best for:Stable applications, time-sensitive migrations, infrastructure cost reduction

Replatform

Make targeted optimizations during migration to leverage cloud services without full refactoring.

Best for:Applications needing performance improvements, managed service adoption

Refactor / Re-architect

Transform applications to cloud-native architectures for maximum agility and scalability.

Best for:Strategic applications, high-growth systems, competitive differentiation

Replace

Retire legacy systems and implement modern SaaS or custom solutions that better meet business needs.

Best for:Outdated systems, commodity functionality, rapid transformation needs

FAQ

Frequently Asked Questions

Common questions about legacy modernization

How do you minimize risk during legacy modernization?

We use proven risk mitigation strategies including parallel running periods, comprehensive testing automation, phased rollouts, and rollback capabilities. Our incremental approach delivers value continuously while managing risk at every stage.

What happens to our institutional knowledge during modernization?

Preserving institutional knowledge is a priority. We employ knowledge extraction techniques, comprehensive documentation, and stakeholder interviews to capture business rules and logic. This knowledge is embedded in modernized systems and documentation.

How long does legacy modernization typically take?

Timelines vary based on complexity and scope. Simple rehosting can take 3-6 months, while comprehensive refactoring may span 12-24 months. We design programs that deliver incremental value throughout, often with first benefits realized within 90 days.

Can you modernize systems where we've lost source code or documentation?

Yes, we have extensive experience with undocumented legacy systems. We use reverse engineering, code analysis tools, and business process mining to understand system behavior and reconstruct necessary documentation before modernization.
