1. Understand the system
Agree on goals and access, map important components and dependencies, and separate observed behavior from assumptions.
C# AND .NET APPLICATION MODERNIZATION
Modernize legacy .NET applications without losing the rules your business relies on.
When a mature application is hard to change, start by learning how it behaves. IntelliArch helps your team identify dependencies, protect important workflows, and choose practical improvements before committing to a broad rewrite.
The discovery call is about consulting, not Hotel AI.
THE CHALLENGE
Change is risky when important behavior is undocumented.
Older C# and .NET systems can hold years of business decisions in code, database structures, batch jobs, and integrations. A framework upgrade or rewrite may affect invoicing, reporting, customer workflows, or downstream systems even when the intended change seems small.
Modernization starts with evidence: what the application does today, which dependencies constrain change, and which outcomes matter most to the business.
What the work can cover
- Review application structure, runtime and framework dependencies, data flows, and integrations.
- Identify high-risk behavior and add or improve characterization tests where access and scope allow.
- Compare incremental refactoring, framework migration, modular restructuring, and replacement options.
- Plan C#/.NET changes with deployment, operations, and team capability in view.
- Support implementation through architecture guidance, code review, and focused engineering work when agreed.
A CONTROLLED APPROACH
Learn, prioritize, validate, then change.
2. Protect critical behavior
Choose representative workflows and test strategies. Confirm business rules with the people responsible for them.
3. Compare options
Review technical trade-offs, operational constraints, effort ranges, and sequencing with your team.
4. Improve in phases
Work from an agreed backlog, validate changes with tests, and transfer decisions and context to your engineers.
Deliverables depend on the agreed scope
A project may produce a current-state summary, dependency and risk notes, test recommendations, a prioritized modernization backlog, architecture decisions, implementation changes, and a knowledge-transfer session. The discovery call establishes whether an assessment, delivery support, or another next step fits.
Results depend on access to relevant code, environments, documentation, and stakeholders. Business owners must confirm intended policy and behavior. AI may assist analysis but does not determine whether a business rule is correct. Security audits, compliance certification, and a full replacement are not implied; they require separate scope.
