Lotus Notes Migration
Modernize 25 years of
Lotus Notes applications
Lotus Notes / HCL Domino applications are the hidden backbone of thousands of enterprises. LotusScript agents, workflow forms, and document databases encode critical business processes that nobody has documented. DEX extracts and modernizes them.
The Process
20-100x faster than manual development.
More accurate because it's governed.
Every step uses the same engine: AI that works inside a structured framework, not a blank canvas. The output is auditable, testable, and yours to own.
AI documents your entire codebase
The engine parses every source file — LotusScript agents, Notes forms, views, workflow rules, NSF databases — and produces a structured inventory. Every block, every business rule, every dependency chain is catalogued before any transformation begins.
- Full NSF database parsing with agent dependency mapping
- Business rule extraction into structured JSON descriptors
- Complexity scoring per database (agents, forms, views)
- Automated documentation generation
Review the business logic — add improvements
Every extracted rule is presented in a structured review interface. Your team walks through each database, confirms the logic, flags scope changes, and adds improvements — before any code is generated. This is where you document 25 years of tribal knowledge.
- Visual business rule inspector — no LotusScript reading required
- Side-by-side: legacy logic vs proposed modern equivalent
- Flag rules for removal, modification, or enhancement
- Add new requirements directly into the migration scope

Added during reviewAI generates the modern application
The governed AI engine transforms every reviewed rule into production TypeScript code — REST APIs, JSON descriptor screens, and typed validators. Not free-form generation: every output follows the framework's constrained patterns.
- LotusScript → TypeScript with semantic equivalence
- Notes forms → JSON descriptors rendered by the governed runtime
- Document databases → REST API layer with structured storage
- 5-10x fewer AI tokens than free-form generators
Sub Initialize
Dim doc As NotesDocument
Set doc = source.Document
If doc.Status(0) = "Pending"
And doc.Amount(0) > 10000 Then
Call SendToApprover(doc)
End If
End Subconst doc = getDocument(sourceId);
if (
doc.status === 'Pending'
&& doc.amount > 10_000
) {
await sendToApprover(doc);
}Automated testing and live preview
Every generated screen has unit tests derived from the original business rules. A live preview lets your team inspect each screen's layout, logic, and data flow before deployment.
- Unit tests auto-generated from every business rule
- Visual regression testing against legacy screenshots
- Live preview with JSON descriptor inspector
- Side-by-side: legacy screen vs modern screen
Keep building with the AI builder
Migration is day one. The same engine that migrated your Notes databases becomes your tool for building new features, screens, and integrations. A DEX Architect uses the governed AI builder to ship 5-15 new screens per month.
- Same framework, same JSON descriptors, same governance
- Natural language → production screen in 2-4 hours
- Add integrations (ERP, CRM, APIs) without rebuilding
- Every new feature is immediately testable and auditable
Why 20-100x faster?
Manual development regenerates architecture decisions on every feature. The DEX engine generates against a fixed framework with reusable patterns. The AI doesn't think about folder structure, auth, logging, or deployment — it's all built in.

More accurate because every rule has a unit test. More auditable because every screen has a JSON descriptor. More maintainable because the output is standard TypeScript.
