Classic ASP Component Extraction: Recovering 20 Years of Admissions Logic for Higher Ed

The most dangerous code in your university isn't a zero-day exploit; it's the classic asp component handling student admissions that no one has touched since 2004.

For Higher Ed CIOs and Enterprise Architects, the "Admissions Portal" is often a digital palimpsest—layers of VBScript, undocumented business logic, and fragile COM+ objects that have survived five presidential administrations. When 67% of legacy systems lack documentation and the original developers have long since retired, the standard "Big Bang" rewrite isn't just risky; it’s a statistical suicide mission. With 70% of legacy rewrites failing or exceeding their timelines, the cost of guessing what your legacy code does is simply too high.

TL;DR: Modernizing Higher Ed admissions doesn't require manual code archaeology; by using Replay for visual reverse engineering, you can extract 20 years of business logic from a classic asp component into documented React components in days, reducing modernization timelines by 70%.

The $3.6 Trillion Black Box: Why Classic ASP Component Extraction is Non-Negotiable#

Global technical debt has ballooned to $3.6 trillion, and Higher Ed is a significant stakeholder in that figure. Most admissions systems built in the late 90s and early 2000s rely on a classic asp component architecture where the UI is tightly coupled with the business logic.

When you attempt to modernize these systems, you encounter the "Archaeology Trap." Your team spends months digging through

files, trying to understand how a specific scholarship eligibility flag is calculated. Is it in the VBScript? Is it a stored procedure? Or is it buried in a compiled DLL that hasn't been recompiled in a decade?

The Cost of Manual Modernization#

Manual extraction is a grueling process. On average, it takes 40 hours per screen to manually document, architect, and rewrite a legacy interface. In a typical admissions suite with 50+ screens (applications, financial aid, international student tracking, etc.), you are looking at 2,000 hours of manual labor before a single line of production-ready modern code is written.

Recovering 20 Years of Admissions Logic Without the Archaeology#

The traditional way to handle a classic asp component involves reading the source code. But the source code only tells you what the system might do. It doesn't tell you how users actually interact with it or how the state changes during a complex multi-page application process.

Replay shifts the paradigm from "Code Archaeology" to "Visual Reverse Engineering." Instead of reading 20-year-old VBScript, you record the actual workflow of an admissions officer or an applicant. Replay captures the DOM changes, the network requests, and the state transitions.

💰 ROI Insight: By moving from manual extraction (40 hours/screen) to Replay (4 hours/screen), an enterprise saves approximately $5,400 per screen in developer salary costs alone, assuming a $135/hr fully-loaded rate.

Step 1: Recording the Source of Truth#

In a regulated environment like Higher Ed (subject to FERPA and HIPAA), you cannot afford to miss edge cases. You record a session where an admissions officer processes a non-traditional student application. Replay captures every interaction with the classic asp component, creating a "video as a source of truth."

Step 2: Component Identification#

Replay’s AI Automation Suite analyzes the recording. It identifies recurring UI patterns—like that complex "Previous Education" grid that appeared in 1999—and maps them to modern React components. It doesn't just copy the HTML; it understands the underlying data structures.

Step 3: Extracting Business Logic into API Contracts#

The most valuable part of a classic asp component isn't the UI; it's the validation logic. Replay automatically generates API contracts based on the observed network traffic and form submissions. This ensures that your new React frontend talks to your legacy (or modernized) backend with 100% fidelity.

typescript
// Example: Extracted logic from a 20-year-old Admissions Component
// Generated by Replay Visual Reverse Engineering

interface AdmissionsFormProps {
  studentId: string;
  residencyStatus: 'InState' | 'OutState' | 'International';
  creditHours: number;
}

/**
 * @description This component replaces the legacy 'Admin_Student_Calc.asp' 
 * logic which handled complex tuition waivers based on residency.
 */
export const TuitionCalculator: React.FC<AdmissionsFormProps> = ({ 
  studentId, 
  residencyStatus, 
  creditHours 
}) => {
  const [tuition, setTuition] = useState<number>(0);

  // Replay extracted this specific conditional logic from 
  // the legacy VBScript behavior during recording
  useEffect(() => {
    let baseRate = residencyStatus === 'InState' ? 350 : 850;
    if (residencyStatus === 'International') baseRate = 1200;
    
    // Legacy logic preserved: 10% discount for credits > 15
    const multiplier = creditHours > 15 ? 0.9 : 1.0;
    setTuition(baseRate * creditHours * multiplier);
  }, [residencyStatus, creditHours]);

  return (
    <div className="p-4 border rounded shadow-sm">
      <h3 className="text-lg font-bold">Estimated Tuition</h3>
      <p className="text-2xl">${tuition.toLocaleString()}</p>
    </div>
  );
};

The Anatomy of a Classic ASP Component Extraction#

When we talk about a classic asp component, we are often dealing with "Spaghetti Code" where SQL queries are embedded directly in the middle of HTML tags.

⚠️ Warning: Attempting to "clean up" legacy ASP code while rewriting it manually often leads to "Feature Creep" and "Logic Drift," where the new system behaves differently than the old one, causing data corruption in the student information system (SIS).

Mapping State Transitions#

In a legacy admissions portal, state is often managed through hidden form fields or session variables that are difficult to track. Replay’s "Blueprints" editor allows you to see exactly how the state evolves.

If a student selects "Veteran Status," and three new fields appear while a background check is triggered, Replay documents this flow automatically. You no longer need to guess which classic asp component triggered the event.

Generating E2E Tests Automatically#

One of the biggest hurdles in Higher Ed modernization is regression testing. How do you know the new system works exactly like the one built in 2002? Replay generates End-to-End (E2E) tests (Playwright/Cypress) based on the recorded legacy workflows. You can run these tests against your new React build to ensure parity.

• •Legacy Input: Student fills out form in ASP.
• •Replay Action: Captures input/output and state change.
• •Modern Output: Generates a test case that verifies the React component produces the same state change.

From Black Box to Documented Codebase#

The goal of using Replay isn't just to get to React; it's to ensure you never end up in "Legacy Hell" again. By using the Library (Design System) and Flows (Architecture) features, you create a living documentation of your admissions logic.

Technical Debt Audit#

Before you even begin the extraction of a classic asp component, Replay provides a Technical Debt Audit. This identifies:

1. •Dead Code: Logic paths that are never reached in real user workflows.
2. •Redundant Components: Five different versions of a "Date of Birth" picker used across the portal.
3. •Security Vulnerabilities: Identifying where legacy components might be exposing PII (Personally Identifiable Information) in ways that violate modern SOC2 or HIPAA standards.

📝 Note: For Higher Ed institutions, Replay offers On-Premise deployment. This is critical for maintaining compliance with university data governance policies that forbid sending sensitive student data to third-party cloud AI services.

Case Study: Recovering the "Scholarship Matrix"#

A major state university had a classic asp component called

. It was 4,500 lines of VBScript. It determined eligibility for $50M in annual financial aid. No one knew how it worked, and the university was terrified to touch it.

By using Replay, they:

1. •Recorded 50 different application scenarios (International, Transfer, Athlete, etc.).
2. •Extracted the logic into a set of clean, documented TypeScript functions.
3. •Reduced the modernization time from an estimated 14 months to just 6 weeks.
4. •Saved an estimated $400,000 in consulting fees.

typescript
// Example: Extracted Scholarship Validation Logic
// This logic was previously hidden inside a COM+ DLL called from ASP

export function validateScholarshipEligibility(
  gpa: number, 
  isFirstGen: boolean, 
  satScore: number
): boolean {
  // Logic identified by Replay's AI Automation Suite
  // based on observed successful submissions in legacy system
  if (gpa >= 3.8 && satScore >= 1300) return true;
  if (isFirstGen && gpa >= 3.5) return true;
  return false;
}

Frequently Asked Questions#

How long does the extraction of a classic asp component take?#

Using Replay, the initial recording takes as long as the workflow itself (minutes). The extraction into a React component and API contract typically takes about 4 hours per screen, compared to the 40+ hours required for manual reverse engineering.

What about business logic preservation?#

Replay captures the "Visual Truth." By recording the inputs and outputs of the classic asp component, we ensure that the business logic is preserved exactly as it functions in production today, rather than how it was supposed to function when it was documented 15 years ago.

Does Replay require access to the legacy source code?#

No. Replay works through Visual Reverse Engineering. It observes the application's behavior in the browser. This is particularly useful for Higher Ed institutions that may have lost the source code for certain compiled components or are dealing with third-party legacy integrations.

Is Replay compliant with Higher Ed security standards?#

Yes. Replay is built for regulated environments. We are SOC2 compliant and HIPAA-ready. For institutions with strict data residency requirements, we offer an On-Premise version that ensures no student data ever leaves your network.

Can Replay handle complex, multi-step forms?#

Absolutely. Replay’s "Flows" feature is designed specifically to map out complex, multi-page architectures. It tracks state across sessions, ensuring that even the most convoluted admissions workflows are documented and extracted accurately.
