Service package
.NET and SQL Modernization Blueprint for Business-Critical Systems
A three-to-five-week blueprint for systems where hidden business rules, stored procedures, reports, and old UI workflows must be mapped before any replacement can be trusted.
Legacy-system risk reduction
Starting from $30k.
Buyer fit: Application owners facing rewrite pressure, undocumented rules, or fragile release paths.
Timeline: Typical duration: 3–5 weeks.
Scope boundary: Not a rewrite guarantee; implementation scope should follow the blueprint and be validated by tests.
Sample artifact: Modernization blueprint with explicit behavior-preservation checkpoints.
Deliverables
- parity-validation plan
- stored-procedure risk summary
- comparison-screen design
- target architecture map

Service detail
Who this package is for, what it covers, and how acceptance is reviewed
The page separates buyer fit, technical scope, integration, governance, client responsibilities, and proof so a technical evaluator can assess the package without relying on generic claims.
Who this is for
- Owners of Web Forms, Classic ASP, VB.NET, ASP.NET MVC, or SQL-heavy applications.
- Teams discussing a rewrite without reliable parity coverage.
- Organizations needing a phased modernization backlog and service seams.
Who this is not for
- A big-bang rewrite estimate based on superficial code counts.
- A guarantee of zero defects or zero regression without scoped testing and acceptance evidence.
- Cloud migration marketing without analysis of current behavior.
Systems and workflows in scope
- ASP.NET / Web Forms / MVC applications
- Classic ASP and VB.NET applications
- SQL Server stored procedures and jobs
- Reports, exports, approval flows, and scheduled processes
- Existing APIs and integration boundaries
Problems this package answers
- Which behavior must remain identical?
- Which SQL rules are undocumented?
- Where can an API seam be introduced safely?
- Which comparison scenarios represent production risk?
- How should rollback and staged release work?
Technical approach
Implementation depth without unsupported guarantees
The exact architecture depends on the system, evidence, access, and risk. These sections show the normal design surface and the boundaries buyers should expect to review.
Technical design
- Legacy behavior map across forms, services, jobs, reports, and SQL
- Database hotspot review covering stored procedures, coupling, indexing, locking, and transaction boundaries
- API seam candidate matrix and dependency map
- Parity test plan with representative scenarios and expected results
- Sequenced modernization backlog with rollback checkpoints
Integration and data handling
- Existing identity, data, and reporting contracts are treated as constraints until explicitly changed.
- New ASP.NET Core or API seams are planned around observable boundaries.
- Database change strategy is separated from application change strategy where risk requires it.
Security, review, and governance
- Permission and role behavior inventory
- Data-flow and sensitive-field review
- Release and rollback controls
- Audit-log preservation where required
- No unsupported compliance guarantees
Timeline and responsibilities
What the client provides and what acceptance means
The published timeline assumes timely access to the agreed evidence, system owners, reviewers, and decision makers. Delays in access, source ownership, regulated-data handling, or review can change delivery sequence without changing the public price floor.
Client inputs
- Access to representative code and database objects through a secure channel
- Business owners for high-risk workflows
- Known defects and production incidents
- Existing test suites and release notes
- Deployment and rollback constraints
Acceptance criteria
- Approved legacy behavior map
- Agreed parity scenarios and test strategy
- Prioritized service seams
- Risk-ranked modernization backlog
- 90-day implementation sequence and decision notes
Example artifacts
- Legacy behavior map
- SQL-side business-rule review
- API seam candidate matrix
- Parity test plan
- Comparison-screen specification
- 90-day modernization roadmap
Package FAQ
Questions to resolve before the engagement begins
Why not estimate a rewrite immediately?
Because code volume does not reveal hidden SQL behavior, approval rules, reports, or operational dependencies that determine migration risk.
Does the blueprint require moving to microservices?
No. Service boundaries are selected based on risk and value, not a predetermined architecture style.
What does behavior preservation mean?
It means defining which observable inputs, outputs, calculations, permissions, and workflow states must match before a replacement is accepted.
Next step
Confirm fit before sharing private system details.
Use the fit call for an early conversation or request assessment scope when the buyer, system, and decision are already clear.
Next step
Start with a short fit call, then scope the assessment.
The first conversation should decide whether the next step is a fixed-scope assessment, modernization blueprint, governed AI pilot, or reliability review.
