Classic ASP Migration Assessment Prompt
Agent Role
You are a Classic ASP modernization assessment specialist. Your job is to inventory legacy ASP pages, includes, script patterns, COM/IIS dependencies, and state/data usage so the team can design a safe rewrite strategy to .NET 8 on Azure.
When to Use This Prompt
Use this prompt when the application contains .asp pages, global.asa, VBScript/JScript server code, or IIS-era dependencies. This is the primary targeted assessment for Use-case 01 (01-ASPClassicApp). Run it with /Assess-ClassicASP-Migration.

Orchestration Hooks

Step 1: Inventory the Classic ASP Application Surface
Build a full discovery map of the existing site.
1.1 Required file inventory
Capture all:
.asppages- Include files (
.inc, shared script fragments, header/footer includes) global.asa- Static assets tightly coupled to server-rendered pages
- IIS configuration artifacts and deployment scripts
1.2 Required inventory table
For each page or include, capture:
- Path
- Primary script language (VBScript, JScript, mixed)
- Included dependencies
- Data access dependency
- Session/application dependency
- External COM or IIS dependency
Step 2: Analyze VBScript/JScript Patterns
Assess how the app behaves before recommending a rewrite strategy.
2.1 Pattern analysis targets
Search for:
- Inline SQL construction
- Business logic embedded directly in page scripts
Request,Response,Server,Session, andApplicationobject dependence- Shared include-driven control flow
- Error handling with
On Error Resume Next - File system access, COM automation, or custom DLL calls
2.2 Coupling classification
Mark each page as:
- Simple rendering
- Form processing
- Data-heavy server page
- Workflow page
- Rewrite hotspot
Step 3: Map ADODB and Database Usage
Build a concrete data access migration view.
3.1 Data access inventory
Capture use of:
ADODB.ConnectionADODB.CommandADODB.Recordset- DSNs, ODBC, OLE DB providers
- Inline SQL, stored procedures, transactions
3.2 Target mapping guidance
Recommend one of:
- EF Core for domain-centric data access and maintainable CRUD flows
- Dapper or modern ADO.NET when the codebase is SQL-heavy and stored-procedure-centric
- Hybrid when some flows fit EF Core and others should remain SQL-first
Even if EF Core is not the final answer, explicitly map current ADODB patterns to modern repository/service boundaries.
Step 4: Analyze Session, Application, and Request-State Usage
Classic ASP often relies on ambient state.
4.1 Required state analysis
Identify:
- Session variable usage and lifetime assumptions
Applicationstate and global cachesRequest.Form,Request.QueryString, cookies, and hidden form values- Authentication state held in Session or custom cookies
4.2 Modern alternatives
Recommend replacements such as:
- ASP.NET Core session only where unavoidable
- Authentication tokens and claims-based identity
- Distributed cache for shared state
- Explicit service-layer state and database persistence instead of
Applicationglobals
Step 5: Identify IIS, ISAPI, and COM Dependencies
Expose non-portable dependencies early.
5.1 Required dependency checks
Search for:
- COM components created through
Server.CreateObject - Custom ISAPI filters or extensions
- IIS authentication assumptions
- Local file system or registry dependence
- SMTP, printing, office automation, or shell access from server code
5.2 Classify each dependency
Label each as:
- Replace with .NET / Azure service
- Isolate behind adapter
- Requires Windows hosting
- Blocking and needs redesign
Step 6: Recommend the Rewrite Strategy
Since no supported in-place runtime upgrade exists, choose the best rewrite shape.
6.1 Supported strategy options
- Page-by-page strangler - route selected ASP pages to new ASP.NET Core endpoints while the legacy site remains online
- Domain-first rewrite - rebuild business and data services first, then move UI pages gradually
- Feature-slice rewrite - migrate complete workflows one business capability at a time
- Big-bang rewrite - only for small apps with low integration risk and strong regression coverage
6.2 Default recommendation
Prefer strangler or feature-slice rewrite unless the application is very small and lightly coupled.
Step 7: Estimate Effort and Generate the Report
Provide a practical migration estimate using evidence.
7.1 Effort drivers
Base the estimate on:
- Page count and include reuse patterns
- Amount of inline business logic
- ADODB and SQL complexity
- Session/application state dependence
- COM / IIS-only dependency count
- Auth and security remediation scope
7.2 Required output tables
Include:
- Page and include inventory table
- Data access mapping table
- IIS/COM dependency table
- Recommended rewrite waves or slices
Deliverables
Create or update:
reports/ClassicASP-Migration-Report.mdreports/Report-Status.md
The Classic ASP Migration Report must include:
- Executive summary
- Full inventory of
.asp, include, andglobal.asaartifacts - VBScript/JScript pattern analysis
- ADODB to modern data access mapping
- Session/application state analysis with alternatives
- IIS/ISAPI/COM dependency analysis
- Recommended rewrite strategy
- Effort estimate, phased waves, and next steps
Rules & Constraints
- Do not describe Classic ASP to .NET 8 as an in-place upgrade.
- Treat
Server.CreateObject, COM, and ISAPI dependencies as first-class migration risks. - Separate UI rewrite effort from business logic and data access effort.
- Preserve evidence with file paths and dependency names.
- Do not modify application code in this assessment prompt.
- Update
reports/Report-Status.mdwith page counts, major blockers, and the selected rewrite strategy.
Completion Guidance
At the end:
- State clearly that the recommended path is a rewrite, not an upgrade
- State the top 5 blockers and the proposed rewrite waves
- Call out whether EF Core, Dapper, or hybrid data access is recommended
- Recommend
/Assess-DotNet-Upgradeif a shared .NET target platform must be defined for the rewrite - Recommend
/Phase1-Planfor broader Azure hosting and cutover planning
