Why teams pick LegacyMap
Most organisations that need to modernise their technology estate do not have a clear picture of what they have. Applications accumulate over years, ownership changes, documentation is out of date, and the integration dependencies between systems are known to individual engineers rather than documented anywhere. Before you can plan a modernisation programme, you need an accurate map.
LegacyMap is the tool for producing that map and turning it into a plan. The assessment rubric gives each system a consistent score on the dimensions that determine modernisation priority — not just "how old is it" but "how hard is it to change, how much risk does it carry, and how much does the business depend on it." The combination of these scores with the integration dependency graph identifies the systems that are both high-risk and high-dependency — the ones that block everything else and need to move first.
The modernisation option analysis for each system prevents the default assumption that every legacy system needs a rebuild. The five options — rehost, refactor, re-platform, rebuild, retire — have very different cost and risk profiles. A system that is architecturally sound but running on unsupported infrastructure is a rehost. A system with a good domain model but a monolithic deployment is a re-platform. A system with fundamental data model problems is a rebuild. LegacyMap makes these distinctions explicit per system.
Who it is for
LegacyMap is used by CIOs and CTOs planning multi-year technology programmes, programme managers running platform modernisation initiatives, enterprise architects documenting and rationalising the application estate, and management consultants delivering digital transformation roadmaps.
