Top Reasons to Migrate IIS-Based .NET Framework Applications to Azure

icon

Maintaining on-prem servers, licenses, and manual upkeep drains budget. No innovation.

icon

Each release risks downtime. Weekend cutovers and fragile rollbacks raise team burnout.

icon

Weak encryption, identity gaps, and missing audits increase HIPAA/GDPR/SOC 2 compliance risk.

icon

Tight bound to Windows and on-prem data makes cloud and mobile integration hard.

icon

Short-staffed teams repeat legacy patterns to maintain aging .NET instead of innovating.

.NET Application Migration Services to Azure That Modernize Legacy Systems

We migrate .NET apps to Azure with a phased plan tied to ROI, compliance, and scale. With Azure IIS as a service, Corsac keeps releases steady and converts legacy IIS and SQL into measurable cloud efficiency with minimized downtime.

modernization-solution

Application Assessment & Migration Planning

We run a data-based audit of systems, IIS, and data flows. You get a phased roadmap that shows what to keep, what to change, risks, and ROI, plus a cutover plan that minimizes downtime and keeps work moving.

IIS & Infrastructure Migration

Our team moves outdated IIS and servers to managed Azure environments. We shift workloads so they auto scale, tighten security, cut hardware spend, and make operations simpler and more predictable.

Code Modernization (.NET Framework → .NET 6/8)

Instead of a risky and costly rewrite, Corsac upgrades to .NET 6/8, removes legacy dependencies, and refactors hotspots. Business logic will stay intact while performance, maintainability, tests, and API-first integration improve.

Database Migration & Optimization

We migrate SQL Server to Azure SQL or Managed Instance with staged replication and tuning. Our team makes indexes, queries, and sizing optimized for speed and cost, while encryption and backups are aligned to regulatory compliance.

Cloud-Native Refactoring & Containerization

We take monolithic systems to cloud architectures where it pays off. It makes releases quicker and scaling easier. This way, you keep core logic and avoid vendor lock-in to be able to evolve as fast as your strategy.

DevOps Enablement & Continuous Delivery

Corsac wires automation and clear governance into every pipeline to prevent schedule drift and unplanned outages. Our DevOps practice speeds deploys, raises reliability, and gives leaders live visibility into cost, speed, and quality.

What Makes Corsac a Trusted Partner in .NET Application Migration to Azure

Modernization is our core specialization

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.

Square icon

Integration vs. Disruption

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.

Square icon

Identification of hidden expenditures

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.

Square icon

AI & Emerging Tech Enablement

We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.

Square icon

Fighting Tech Stagnation

Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.

Respect for Existing Architecture and Leadership

We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.

4 Steps to Accelerate Digital Transformation with IIS .NET Framework Migration to Azure

Assessment & Cloud Readiness Analysis

We start with a full audit of your current system, dependencies, data flows, and compliance posture. The result is a factual plan that maps risks and effort, so Azure IIS migration is naturally aligned with your business continuity plan.

Application & Infrastructure Modernization

We untangle legacy dependencies, split file storage, sessions, and replace fragile servers with managed Azure. Core logic stays the same. But we modernize components and prepare the stack to migrate website to Azure without disrupting live operations.

Migration to Azure Environment

Square

We move IIS workloads to Azure App Service (IIS-as-a-Service) for managed scale and less maintenance.

Square

We upgrade .NET Framework apps to .NET 6/8 for better performance.

Square

We shift data to Azure SQL or SQL Managed Instance with tuning and built-in disaster recovery.

Square

We keep on-prem and cloud in sync during migration.

We enforce zero-trust, encryption, and Azure Active Directory identity.

Square

We ship via CI/CD with rollback points and live monitoring.

We validate each step with DevOps checks for stability and compliance.

Optimization, Monitoring & Continuous Improvement

After migration, Corsac keeps Azure lean and accountable. We right-size resources, automate cost tracking, and monitor with Azure Monitor and App Insights. Our governance dashboards keep operations secure, efficient, and audit-ready.

    Frequently Asked Questions

    We use phased cutovers and hybrid sync. Our team validates each step, keeps both sides live, and switches only when metrics match. This keeps migrating web application to cloud controlled, and with minimized downtime.

    Azure IIS here means hosting your IIS app on Azure App Service for Windows. Microsoft runs the Windows/IIS stack, while we set up CI/CD, scaling, and security. Our Azure IIS service approach manages patches, scaling, and security for you.

    Yes. We preserve domains, SSL, redirects, and caching. We always test crawls before switching. During migrate web steps, monitoring catches regressions fast.

    Developers get a clearer workflow – it includes CI/CD for each change, secrets stored in Key Vault, logs and metrics in App Insights or Log Analytics, and infrastructure as code. Migrating IIS .NET Framework Applications to Azure makes releases faster and makes rollbacks simpler.

    Not usually. We refactor targeted parts, keep stable logic, and evolve the rest. This lowers risk while delivering web application migration to Azure benefits quickly.
