Modernization Lifecycle

Risk-averse strategies to ensure zero data loss and business continuity during the transition.

01

Assessment & Audit

We analyze your existing codebase, database schemas, and infrastructure to understand dependencies and technical debt.

02

Strategy Definition

We choose the right path: Rehost (Lift & Shift), Replatform (Cloud Tweaks), or Refactor (Complete Rewrite) based on ROI.

03

Modernization Execution

Agile development phases to upgrade the system. We often use the "Strangler Fig" pattern to replace modules incrementally.

04

Data Migration

Secure transfer of data from legacy storage to modern databases, ensuring integrity, schema mapping, and validation.

05

Cutover & Support

Seamless switch-over to the new system with rollback plans in place. Post-launch monitoring and optimization.

Team Agility

Eliminate Risks

Move away from unsupported platforms and security vulnerabilities found in aging software.

Talent Retention

Attract top developer talent by using modern tech stacks instead of obsolete languages like COBOL or VB6.

Scale on Demand

Leverage cloud elasticity to handle peak loads instantly, paying only for the resources you use.

FAQ

Common Questions

Understanding the modernization journey.

Is a complete rewrite always necessary?

No. We often recommend incremental strategies like the "Strangler Fig" pattern, where we replace specific modules over time, or "Lift and Shift" for quick cloud adoption before refactoring.

How do you ensure data integrity during migration?

We perform extensive data mapping and validation. We run parallel systems during the transition phase to compare outputs and ensure 100% data accuracy before the final cutover.

What about business downtime?

We design our migration plans to minimize or eliminate downtime. By using blue-green deployment strategies, we can switch traffic to the new system instantly once it's verified.

Can you modernize mainframe applications?

Yes. We have experience offloading mainframe processing to the cloud or rewriting COBOL logic into modern languages like Java or C# .NET to reduce licensing costs.
