Focus
Legacy assessment and risk
Inventory of the legacy landscape by domain, dependency and operational risk. We identify modules fit for retirement and those that must be stabilized first. Output: prioritized modernization roadmap.

Legacy modernization and system retirement
Master legacy.
Without downtime.
ERP migration, system consolidation and retirement of historic landscapes in controlled slices. Old and new run in parallel until operations sit safely on the new side. Refurbishment over rip and replace.

Why it matters
Legacy does not fall,
legacy gets replaced.
Every big bang ends in the same headline. We run retirement in slices, with coexistence between the old system and target architecture, controlled routing and clear fallback paths.
Historic ERP, home grown business applications and undocumented interfaces are not an IT problem alone. They lock up capital, block new products and create risk on every release. Still, modernizations regularly fail on the ambition to replace everything at once.
We work along the Strangler Fig Pattern. New services grow next to the old system, take over function by function and are activated through a routing layer. Operations stay stable, risk stays small, progress becomes measurable.
Expertise
What we do for
your legacy landscape.
Four priorities that carry every modernization. Depending on system, dependency and risk we prioritize and slice iteratively.
Focus
Strangler pattern and migration
Slice design by domain, data ownership and interface. New services take over function by function while the old system keeps delivering. Every slice is small enough to revert.
Focus
Integration and coexistence
Routing layer, API facade and event bus bring old and new together. Users notice nothing, data stays consistent, telemetry shows at any moment which side carries which load.
Focus
Data migration and cutover
Schema mapping, consistency checks and automated migration runs with dry run. The final cutover is a confirmed operation, not a leap into the unknown. Rollback plan included.
Approach
Three stages
to a controlled retirement.
Modernization runs in waves, not in one project. We work with architecture, business and operations together, clocked to the slices that your system allows.
01
Inventory
System map, data flows, interfaces and operational risks. Workshops with the teams that actually know the legacy. Output: target picture and prioritized slice list with quantified retirement effort.
02
Migration in slices
Build the routing layer, implement the first services, activate in production behind a feature flag. Every slice is accepted, measured and anchored individually.
03
Operation and retirement
Continuous migration of further modules, decommissioning of old functions, final shutdown. Handover into your operations with documented architecture. Legacy goes offline in a controlled way.
Your value
What you take away
after the mandate.
Demonstrable modernization that does not break on first resistance. No slides, a system state that can keep running.
Continuity
Operations stay stable
Business and customers barely notice the migration. No rollback weekends, no frozen releases, no emergency plans activated in daily work.
Risk
Rollback at any time
Every slice is small, documented and reversible. If a new service fails, the legacy function takes over automatically. No lost data, no lost transactions.
Pace
Measurable progress
Instead of a two year project plan we deliver in sprint sizes. After every slice a part of the legacy landscape is retired in production. Management and business see progress, not slides.
Cost
Running cost drops
Legacy maintenance, specialty licenses and external specialists phase out step by step. The freed budget flows into the target architecture, not into new emergency patches.
