    Why modernize now?

    Legacy applications have become the bottleneck to AI

    71%

    of modernization initiatives have exceeded their planned costs1

    61%

    of organizations have paused, delayed, scaled back or abandoned modernization1

    60%

    of AI projects without AI-ready data will be abandoned through 20262

    What we decide

    Every application gets a deliberate disposition

    Decommission and archive the data

    Exit quadrant: low business value, high complexity. Retire or replace with SaaS.

    When we recommend itLow usage or duplicated capability

    Assess & RoadmapExitDecided in Design

    Retire tab preview

    Keep as is, revisit later

    Keep-it-simple quadrant: rehost or retain until the economics change.

    When we recommend itStable, low-cost, no near-term change needed

    Assess & RoadmapKeep it simpleDecided in Design

    Retain tab preview

    Lift and shift to cloud infrastructure

    Keep-it-simple quadrant: rehost or retain until the economics change.

    When we recommend itData-centre exit deadline, little change budget

    Move with targeted optimizations

    Quick-wins quadrant: replatform or refactor first; ideal lighthouse candidates.

    When we recommend itQuick wins from managed services or containers

    How we modernize

    AI accelerates every stage.With engineers in the loop.

    AI does the slow analysis, conversion and testing across the lifecycle. Our engineers review every change and own what ships.

    01

    Understand

    Code comprehension and auto-documentation of legacy systems.

    02

    Extract

    Business rules, data lineage and dependencies pulled from code.

    03

    Convert

    Assisted code translation and refactoring proposals.

    04

    Validate

    Generated test suites and functional-equivalence checks.

    05

    Operate

    AIOps anomaly detection and incident triage after go-live.

    Every AI-generated change is engineer-reviewed, tested and traceable to its source.

    Engagement models

    Three ways to start, each building on the last

    Assess the portfolio, prove the pattern on one application, then scale in waves.
