Beyond the @Formula: Streamlining Lotus Notes Domino Migration with Visual Reverse Engineering

Your enterprise is likely sitting on a ticking time bomb of @Formula language and nested LotusScript that nobody under the age of 50 understands. For decades, Lotus Notes was the gold standard for collaborative logic, but it has become the ultimate "black box" of technical debt. When you attempt a lotus notes domino migration, you aren't just moving data; you are trying to perform archeology on obscure workflow logic that has been buried under layers of technical debt for thirty years.

According to Replay’s analysis, the primary reason these migrations stall is not the data—it's the UI-driven logic that was never documented. Industry experts recommend that instead of trying to read the source code of a 20-year-old NSF file, you should observe the application in motion.

TL;DR: Manual lotus notes domino migration takes an average of 40 hours per screen and has a 70% failure rate due to undocumented collaborative logic. Replay uses Visual Reverse Engineering to convert video recordings of your legacy workflows into documented React components and Design Systems, reducing migration time by 70% and turning 18-month projects into week-long sprints.

The Invisible Wall of Lotus Notes Domino Migration#

The $3.6 trillion global technical debt crisis is nowhere more visible than in the basement of insurance firms and government agencies running Domino R5 or R6. These systems were built with "collaborative logic"—a mix of email, database, and UI state—that doesn't translate directly to the modern web's Request/Response cycle.

When you start a lotus notes domino migration, you quickly realize that 67% of legacy systems lack any form of documentation. You are left with two choices:

1. •Hire expensive consultants to manually map every "Action Button."
2. •Use Replay to record the workflow and let AI extract the architecture.

Video-to-code is the process of using computer vision and AI to analyze user interface recordings, identifying functional components, state changes, and design patterns to generate production-ready modern code.

Why Traditional Rewrites Fail#

The average enterprise rewrite timeline is 18 months. By the time the migration is finished, the business requirements have changed, and the "new" system is already lagging. In the context of Lotus Notes, the "logic" is often hidden in the UI itself—dynamic hide-when formulas, input validation scripts, and complex view lookups.

Mapping Obscure Collaborative Logic via Video Capture#

The "collaborative" nature of Domino means that a single form might change entirely based on who is looking at it and what the "Status" field says. Traditional static analysis tools fail here because they can't see the "Hide-When" conditions in action.

By using Replay, you record a user performing a specific task—for example, submitting a complex insurance claim. Replay captures every state transition. It sees that when "Status" is "Pending," the "Approve" button appears. It understands that the "Manager" field is being pulled from a lookup.

From NSF Views to React Tables#

One of the hardest parts of a lotus notes domino migration is replicating the "View" logic. Domino views are powerful, allowing for categorized, hierarchical data display that is notoriously difficult to code from scratch in React.

Replay's AI Automation Suite analyzes the video of these views and generates the corresponding TypeScript interfaces and React components. It doesn't just copy the HTML; it understands the intent.

typescript
// Example of a generated React component from a Lotus Notes View recording
import React, { useMemo } from 'react';
import { useTable, useGroupBy, useExpanded } from 'react-table';

interface DominoMigrationRow {
  id: string;
  category: string;
  subject: string;
  lastModified: string;
  status: 'Draft' | 'Pending' | 'Approved';
}

export const CollaborativeView: React.FC<{ data: DominoMigrationRow[] }> = ({ data }) => {
  // Replay identified the "Categorized" logic from the legacy UI recording
  const columns = useMemo(() => [
    { Header: 'Category', accessor: 'category' },
    { Header: 'Subject', accessor: 'subject' },
    { Header: 'Last Modified', accessor: 'lastModified' },
    { Header: 'Status', accessor: 'status' },
  ], []);

  const { getTableProps, getTableBodyProps, headerGroups, rows, prepareRow } = useTable(
    { columns, data },
    useGroupBy,
    useExpanded
  );

  return (
    <table {...getTableProps()} className="min-w-full divide-y divide-gray-200">
      <thead className="bg-gray-50">
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
              <th className="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase">
                {column.render('Header')}
              </th>
            ))}
          </tr>
        ))}
      </thead>
      {/* Table Body Logic... */}
    </table>
  );
};

The Replay Workflow: Modernizing in Weeks, Not Years#

To execute a successful lotus notes domino migration, we follow a three-tier architectural approach within the Replay platform.

1. The Library (Design System Generation)#

Instead of manually creating a new UI kit, Replay's Library feature extracts colors, typography, and component patterns directly from your legacy recordings. It identifies that your "Standard Domino Button" is used in 400 places and creates a single, reusable React component. This enforces consistency—something legacy Domino apps desperately lack.

2. The Flows (Architecture Mapping)#

This is where the "video capture" shines. By recording different user personas (e.g., an Initiator, a Reviewer, and an Admin), Replay maps the "Flows." It visualizes the state machine of your application. You can see more about this in our article on Modernizing Legacy Workflows.

3. The Blueprints (The Code Editor)#

Once the flows are mapped, Replay generates the "Blueprints." These are the functional React components. Unlike generic AI code generators, Replay's code is grounded in the visual reality of your existing system. It ensures that no "obscure logic" is left behind.

typescript
// Replay-generated logic for a legacy "Hide-When" formula
// Original: @If(Status = "Closed"; @IsMember("[Admin]"; @UserRoles); @True)

interface ActionProps {
  status: string;
  userRoles: string[];
}

const EditActionButton: React.FC<ActionProps> = ({ status, userRoles }) => {
  const isAdmin = userRoles.includes('[Admin]');
  
  // Replay correctly interpreted the complex visibility logic from the recording
  const isVisible = status !== 'Closed' || isAdmin;

  if (!isVisible) return null;

  return (
    <button className="bg-blue-600 text-white px-4 py-2 rounded">
      Edit Document
    </button>
  );
};

Security and Compliance in Regulated Industries#

Most Lotus Notes environments exist in highly regulated sectors: Financial Services, Healthcare, and Government. A lotus notes domino migration in these fields cannot use public, unvetted AI tools.

Replay is built for these environments. We are SOC2 and HIPAA-ready, and for the most sensitive workloads, we offer On-Premise deployment. Your proprietary collaborative logic and sensitive data never leave your network.

Industry experts recommend that security-conscious organizations prioritize platforms that provide "Exportable Documentation." Replay generates full technical specs alongside the code, ensuring that the "Black Box" is finally opened and documented for the next generation of engineers. You can read more about our Security Architecture for further details.

The Cost of Inaction#

Every day you delay your lotus notes domino migration, the risk grows. The pool of LotusScript developers is shrinking, and the underlying hardware/OS support for Domino is becoming a liability.

By shifting from a "Code-First" to a "Visual-First" migration strategy, you bypass the need to decode thousands of lines of 1990s-era script. You focus on the user experience and the business outcome.

According to Replay's analysis, companies that use visual reverse engineering see a 70% average time savings. This allows the internal IT team to focus on innovation rather than just keeping the lights on for a legacy server.

Frequently Asked Questions#

How does Replay handle data migration from Domino NSF files?#

Replay focuses on the UI and Logic layer. While we generate the React components and API schemas, the data migration (moving records from NSF to SQL/NoSQL) is typically handled via ETL tools. However, Replay provides the "Blueprint" for what the new data structure should look like based on how the UI interacts with the data.

Can Replay understand LotusScript and @Formula?#

Replay doesn't "read" the script in the traditional sense. It "observes" the result of the script through video capture. If a LotusScript agent runs and changes the UI state, Replay identifies that state change and builds the modern equivalent in React/TypeScript. This avoids the "Garbage In, Garbage Out" problem of direct code translation.

Does the generated code follow modern best practices?#

Yes. Replay generates clean, modular TypeScript code using industry-standard libraries like Tailwind CSS and React Query. The goal is to move you away from proprietary legacy structures to a modern, maintainable stack.

What industries benefit most from this visual migration approach?#

Regulated industries like Insurance, Banking, and Government are the primary users. These sectors have massive, complex Domino footprints where documentation is missing and the risk of a failed migration is high.

How long does it take to see results with Replay?#

Most teams can generate their first set of documented React components within the first week of using the platform. A full screen migration that used to take a week (40 hours) can be completed in a single afternoon (4 hours).
