Legacy Software Modernization
We replace the software your business depends on.
End-to-end modernization for business-critical systems — from assessment through go-live and managed operation.
For owners and technical leads
When support is ending, integrations fail, or the system can no longer be maintained safely — start with a fixed-price assessment. Mid-sized companies, mostly Switzerland, Germany, and Austria. Pricing stays private; no timeline theatre before requirements are known.
Assess
We map the existing systems, business processes, users, and data flows to reveal the current state and its pain points. Complexity becomes readable — the same parts, newly understood.

Get the assessment overview
A concise PDF on what the fixed-price assessment covers — complexity, users and roles, data structures, dependencies, and business criticality. Leave an email; we send the overview.
We use your email only to send the overview and follow up on assessment interest. No newsletter by default.
Define
Understand how systems, processes, and data flows relate as they are — before shaping the target architecture. Relationships become visible; dependencies become workable.
Build
The defined structure becomes a functioning connected system — prototype, implement, integrate, and test. Working software, not a handoff of slides.
Migrate
We analyse the legacy data structure, define a code-driven repeatable migration approach, and select the data to be carried into the new system.
Operate
Ongoing managed service with clear SLAs, continuous improvements, and options from self-managed to full-service operation — hosting, ITSM, and on-call when needed.
Start with an assessment
Fixed-price entry. Unfiltered view of the existing system — then define, build, migrate, and operate with snrt.
