Legacy application modernization
Illustrative example, not a client result.
Ksoft modernizes legacy applications to secure, cloud-native platforms - with zero planned downtime and a written roadmap before any build begins.

summary
Ksoft Technologies modernizes legacy applications to secure, cloud-native platforms for SMEs and mid-market businesses, using a 6R framework (Rehost, Replatform, Refactor, Rearchitect, Rebuild, Replace) to pick the right strategy per system. Every engagement starts with a free 7–14 day Discovery Sprint that produces a written audit and fixed roadmap before any build begins. Migrations run with zero planned downtime: the legacy system stays live in parallel until the new one is tested and approved for cutover. Typical engagements range from $10,000 to $50,000 USD depending on migration path and complexity. NDA signed before any system, code, or data is reviewed. Based in Cherpulassery, Kerala, India.
Is your system a liability yet?
The U.S. Government Accountability Office found that over 70% of the federal IT budget request for fiscal year 2017 went to operating and maintaining existing systems, leaving less than 30% for new work. (GAO-16-468) If more than a couple of these look familiar, you're already overdue.
The Ksoft 6R framework
Every legacy system has different dependencies and risk tolerance. The 6R framework decides which of six paths fits yours - before a line of code is touched.
Rehost
Lift and shift to cloud infrastructure with no code change. Fastest path for stable systems chasing cloud cost and uptime.
Replatform
Move to a modern cloud platform with targeted upgrades - database, containers, OS - without a full rewrite.
Refactor
Restructure existing code for cloud-native performance. Right when the business logic is sound but the architecture isn't.
Rearchitect
Structural redesign, typically monolith to microservices, for systems that can't scale as they are.
Rebuild
Redevelop from scratch on a modern stack, when the legacy code is beyond repair or undocumented.
Replace
Retire the system entirely for a purpose-built or SaaS alternative suited to your industry.
What happens, and when
Typical timeline for a full refactor or rebuild. Rehost and replatform projects run shorter. Your written roadmap confirms the exact timeline.
Weeks 1–2
We map every dependency, integration, data flow, and risk in your current system. Output: a written audit and fixed roadmap, confirmed before any build begins. Free, no obligation.
Weeks 2–4
Our architects design the target state - cloud infrastructure, database schema, API layer, security model. You approve it before we build.
Weeks 4–16
Core modules move first, then integrations, then data. Your existing system stays live throughout - no forced downtime.
Weeks 14–18
Full regression, load, security, and user acceptance testing, against your team's real workflows, before sign-off.
Weeks 18–20
Planned cutover in a low-traffic window. Ksoft stays on-call for 30 days post-launch with defined SLA response times.
Months 2–6
Monitoring, performance tuning, and staff training. We don't disappear after launch.

Questions
Timelines depend on the migration path - rehost, replatform, refactor, rearchitect, rebuild, or replace - and the complexity of your system. After discovery, we provide a written audit and a fixed roadmap confirming your exact timeline before any contract is signed.
No planned downtime for business-critical systems. We use a phased, parallel-running approach: your existing system stays live until the new one is fully tested and signed off. Cutover is planned for a low-traffic window, typically a weekend, and the old system stays available as a fallback until your team approves.
Typical Ksoft engagements range from $10,000 to $50,000 USD depending on scope - from straightforward rehost or replatform work to complex rearchitecture with full data migration and third-party integrations. You receive a written scope and fixed roadmap after your free Discovery Sprint, before any build commitment.
Yes. This is our default for all projects. We run both systems in parallel and keep data in sync until your team approves cutover, so daily operations carry on.
Yes. An NDA is signed before we access any system architecture, code, or data. All Ksoft engineers operate under strict confidentiality agreements.
We work across manufacturing, healthcare, and education, and also with logistics, finance, and B2B SaaS companies. The Discovery Sprint maps your industry's data and compliance needs before any build begins.
We work with legacy stacks including COBOL, VB6, legacy .NET Framework, Java EE, PHP 5.x, classic ASP, and desktop applications built in Access, Delphi, and FoxPro. The discovery phase confirms the migration path for your specific stack.
