Legacy Software Modernization

We replace the software your business depends on.

Replace business-critical systems: assessment, go-live and managed operation from one partner.

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.

Straight answers

What is legacy software modernization with snrt.?

snrt. replaces the software a business still runs on when the old stack cannot be kept safely. We take that work end to end: Assess, Define, Build, Migrate, Operate. Entry is a fixed-price assessment. We map systems, processes, users, and data flows as they stand today, pain points included, before anyone draws a target architecture. Same parts, newly understood. Pricing stays private. We do not invent timelines before requirements are known. Mid-sized companies, mostly Switzerland, Germany, and Austria. After assessment we name how systems, processes, and data flows relate: dependencies, ownership, and a scope that can survive build. Then we prototype, implement, integrate, and test until that structure runs as connected software. For migration we analyse the legacy data structure, define a code-driven repeatable path, and choose which data moves. Operate is managed service with clear SLAs, from self-managed to full-service, with hosting, ITSM, and on-call when needed.

When should you start with an assessment?

Start when support is ending, integrations keep failing, or the system can no longer be maintained safely. Owners and technical leads usually know the symptoms before they know the replacement plan. Security exposure and an inability to evolve the system show up the same way. The fixed-price assessment is the entry: an unfiltered view of complexity, users and roles, data structures, dependencies, and business criticality. We send a short PDF overview on request. Leave a work email and we send it. That address is only for the overview and follow-up on assessment interest. No newsletter by default. Audience: mid-sized companies, mostly Switzerland, Germany, and Austria. After assessment, Define, Build, Migrate, and Operate run with snrt. as one partner through go-live and managed operation. Prices stay private. No timeline theatre before requirements are clear.

Assess

We map systems, processes, users and data flows as they are today — including the pain points. Same parts, newly understood, without timeline theatre.

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

How systems, processes and data flows relate before we draw the target architecture. Dependencies named; ownership agreed; scope that can survive build.

Build

Prototype, implement, integrate and test until the defined structure runs as connected software. Working system — not a slide handoff.

Migrate

Analyse the legacy data structure, define a code-driven repeatable migration, and choose which data moves into the new system.

Operate

Managed service with clear SLAs — from self-managed to full-service. Hosting, ITSM and on-call when needed; improvements as the system settles.

Fixed-price entry. Unfiltered view of the existing system — then define, build, migrate, and operate with snrt.
