Timing Matters
Top Reasons to Modernize and Migrate Your Application to Azure
■Your on-prem or IIS hosting is expensive to maintain and hard to secure.
■Your releases are slow because the architecture is tightly coupled and brittle to change.
■Your team depends on a few developers who carry undocumented logic in their heads.
■Your platform's fragile hosting and legacy servers cause unexpected outages.
■Your system cannot scale cleanly when usage spikes or the business expands.

Azure App Migration Services to Modernize Legacy Systems
Azure app migration with Corsac is a controlled, reversible move from on-prem/IIS/.NET to Azure, with parallel run, real performance gains, lower infra cost, and compliant, predictable releases.
Azure Application Assessment & Migration Roadmap
We map IIS, COM, file and library dependencies, check frameworks, APIs and DB health, and chart critical workflows. Next, we evaluate risks, map recovery, build a total cost-of-ownership model, and suggest Azure services optimized for speed, profit, ROI, and scaling.
Refactoring & Application Modernization for Azure
Our experts modernize .NET Framework to .NET 6/8, eliminate server dependencies using modern configuration-as-code, and split large monoliths into services and APIs. We also add modern auth (AAD, OAuth, or OIDC), and set up CI/CD in GitHub Actions or Azure DevOps.
Post-Migration Optimization, Monitoring & Support
Our team optimizes performance using App Insights and Azure Monitor, hardens your security through Key Vault, identity access, and network rules. Corsac cuts costs with Azure Advisor and right sizing, trains the team, and plans next steps with microservices, events, and containers.
4 Steps to Successfully Migrate Your Web App to Azure
Step 1. Assessment & Azure Migration Strategy
We audit your legacy system, map hidden dependencies, assess risks, and pick the best migration model (rehost, replatform, or refactor), then deliver an Azure migration roadmap aligned with business continuity and the highest ROI.
Step 2. Architecture Preparation & Code Modernization
We restructure legacy architecture and code so it is cloud ready and maintainable. We decouple monoliths, improve modularity, replace deprecated libraries, harden security, and prepare the system for Azure-native services.
Step 4. Testing, Deployment & Testing, Optimization & Post-Migration Support
We validate critical flows, match performance to the old system, and tune cloud usage to avoid overspend. After deployment, we refine observability, train your team, and leave a clear modernization roadmap.
What Makes Corsac a Trusted Partner in Azure Application Migration
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.
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.
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.
Respect for Existing Architecture and Leadership
We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.
Fighting Tech Stagnation
Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.
AI & Emerging Tech EnablementAI & 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.

FAQ
How do you migrate application to Azure without breaking day-to-day operations?
Our team breaks the transition into stages and maintains both legacy systems and Azure environments run in parallel before the final switch. Data is synchronized, key workflows are tested under real load, and only then we switch traffic. This way, we can migrate web apps to Azure with minimized downtime.
What is the difference between lift-and-shift and modernization on Azure?
Lift-and-shift mostly moves virtual machines, IIS sites, and services. However, it also keeps most of the old constraints. Modernization reshapes architecture, tightens security, adds CI/CD, and adopts managed Azure services. So, Azure application migration removes technical debt, not just changes hosting.
How do you estimate ROI before starting an Azure migration project?
We begin with a tech and financial audit: infrastructure bills, release effort, outage impact, and team load. Then, we model different scenarios, including cloud total cost of ownership, risk reduction, and time-to-deliver improvements. You see clear numbers before any app migration to Azure starts. So it is a decision backed by data, not a guess.
Can you migrate just part of a system to Azure first?
Yes, and for many teams this is the safest approach. We usually start with the modules that cause the most cost or risk, set up hybrid connectivity, and move them in stages. This lets you migrate web app to Azure incrementally, keep users working, and prove the benefits before expanding the scope.
What does “ownership handover” look like after migration?
We do not leave you with a black box. Your team gets documentation, architecture diagrams, CI/CD pipelines in your repos, runbooks, and monitoring dashboards. We run training sessions with your developers and ops so they can operate, debug, and extend the new Azure setup themselves.
