Architecture is siloed. Classic ASP apps block clean APIs into ERP/CRM, analytics, and GIS.
Your team battles fragile IIS, manual deploys, costly slow releases, and weekend cutovers.
Your system relies on legacy auth and weak secrets management, raising GDPR/SOC2/HIPAA risks.
Your legacy architecture locks data in, limiting cloud, AI, and automation adoption.
Your releases are risky with no CI/CD or safe rollback. “Maintenance windows” hit business hard.
Since 2007, Corsac has driven complex modernizations for our clients. With our ASP to .NET migration, we reduce client risks, stabilize software releases, and ensure legacy assets produce measurable ROI.

38%We help teams migrate from ASP .NET web forms into modern .NET so you trade friction for performance, security, and scale without breaking business rhythm.
Spend less on maintenance, license, and infrastructure.
Shorten release cycles and see impact sooner with CI/CD and automation.
Keep the system running during transformation with our hybrid coexistence.
Compliance with GDPR, SOC 2, HIPAA, ISO.
Access a large .NET talent pool to reduce staffing risk.
Integrate APIs, business intelligence tools, CRMs, and GIS systems.
For cross-platform deployment, we run .NET Core on Windows and Linux to keep hosting flexible and costs controlled.
With a cloud-ready design, we host in Azure or AWS to fit your stack and compliance.
We ship services as Docker containers on Kubernetes so scaling and rollbacks stay controlled.
We tune async I/O and the runtime so latency stays low.
We design API-first, decoupled services and wire in automated tests and CI/CD so UI, logic, and data integrate cleanly.
Let us help you rebuild what’s holding you back.
Corsac’s ASP.NET migration services modernize legacy apps with transparent delivery in your repo, CI/CD, and no black boxes. We run old and new in parallel with rollback safety and fix architecture, data, and release processes, not just “convert code.”
We aren’t a full-stack agency. We’ve built our team, processes, and tech strategy specifically to tackle legacy issues and help mid-market players scale and innovate.
We integrate with your workflows, minimizing interference with your developers. While utilizing your Git, CI/CD, and tools, we operate independently, letting your team focus on their work.
Your aging system drains your business resources through slow hiring, security gaps, and delayed launches. We reduce these “dark tech debt” losses before they impact your revenue.
We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.
Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.
We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.
We start with a detailed audit of Classic ASP and ASP.NET apps, IIS, and data flows. Then we map reuse, risks, and effort, and design a phased .NET 8 migration roadmap tied to clear ROI, release cadence, and compliance needs.
We refactor legacy ASP and ASP.NET Framework into modular .NET 8 solutions. We untangle tight coupling, replace brittle dependencies, and add security, caching, and tests so the new stack is faster, cloud-ready, and easier to maintain.
Corsac team rebuilds Classic ASP and Web Forms UIs in Blazor or SPA so screens stay modern and mobile-ready.
We swap legacy data access for EF Core or tuned ORMs. Our experts cut query load and lag.
Our engineers move databases to Azure SQL, PostgreSQL with staged cutovers and minimized downtime.
We standardize schemas, add analytics-ready pipelines, and align security with HIPAA, GDPR, and SOC2.
We add tests, DevOps checkpoints, docs, and training so your team can run the new stack confidently.
Finally, we integrate new APIs, stand up CI/CD, and run automated tests across environments. Then we deploy to Azure or hybrid setups with staged cutovers, monitoring, and rollback safety so performance, security, and compliance stay in control.

We focus on modernization for companies unable to grow due to aging systems
We replace only what must be changed, protecting your investment and CTO’s credibility.
HIPAA, HL7/FHIR, SOC2, GDPR, ISO compliance is integrated into every stage.
Integrating into your Git, CI/CD, and workflow tools, we make modernization visible, testable, and traceable
We uncover hidden costs, feature delays, and security gaps and offer ways of their removal
By providing CEOs stakeholder-ready roadmaps and progress metrics, we enable well-grounded transformation
They fulfill your task without seeking to address the issue at the root
Dispersing the focus, they fail to meet specific Healthcare G and other industry requirements
Generalized practices, regardless of the product, team, or business specifics
Initiate full rewrites instead of using the working parts and considering business context
Insufficient collaboration leads to poor handover, with documentation debt and weak enablement.
Development happens in isolation, prioritizing code delivery over actual business value.
We plan ASP to .NET migration as a phased cutover. Old and new apps run side by side, data stays in sync, and we switch traffic only when checks pass. A tested rollback path is always ready, so if something misbehaves we flip back and users keep working.
A Classic ASP to .NET 8 migration starts with an audit of code, data, and integrations. We group the app into modules, then move logic into .NET 8 or ASP.NET Core services, upgrade auth and data access, and release each piece behind tests until the whole flow is stable.
Our ASP migration services cover Classic ASP, Web Forms, and ASP.NET Framework apps. We modernize code into .NET Core or .NET 8, move databases, add APIs, and wire CI/CD plus monitoring. Your team stays on product work while our engineers run the migration independently, only with light touchpoints.
In a full rewrite, you often throw away proven behavior and wait months for parity. In ASP to .NET Core migration we reuse stable flows, refactor only what blocks scale or security, and roll out in slices, so risk, cost, and delivery time stay under control.
If the app is business-critical, yes. A focused Сlassic ASP to ASP.NET upgrade removes old security holes and unsupported components while keeping the behavior users rely on. We right-size the scope so smaller systems get a lean, and cost-appropriate migration path.
