Overview
Migr8IT modernised 28 mission-critical IBM Notes client applications for Mitsubishi Chemical, transforming them into secure self-hosted browser-based platforms while preserving underlying business logic, workflows, and access controls.
The programme delivered modern access across devices while reducing reliance on legacy Notes client infrastructure.
The Challenge
Mitsubishi Chemical relied on 28 mission-critical IBM Notes client applications to support core operational processes across the business.
These applications were deeply embedded in day-to-day operations and built on legacy Notes client architecture, limiting accessibility and long-term maintainability.
In several operational environments, users were required to travel across hazardous areas to access Lotus Notes clients, as laptops could not be safely used on site. This created operational inefficiencies and restricted access to critical systems.
Modernisation was required to improve usability, reduce technical risk, and enable future platform transformation while preserving essential business functionality.

Modernising IBM Notes Applications into Secure Web Platforms

Migr8IT delivered a structured modernisation programme that transformed 28 mission-critical IBM Notes client applications into secure web platforms while preserving core business logic, workflows, security models, and integrations.
Applications were rebuilt using established web technologies, allowing the organisation to retain full control of its infrastructure while removing reliance on the legacy Notes thick-client client architecture.
Crucially, the modernised applications retained the custom operational behaviours users relied on. The web platform preserved:
Innovation Highlight
The modernised web architecture also enabled new operational capabilities that were previously not possible.
During testing, the web applications were successfully accessed through augmented reality (AR) glasses, allowing engineers to interact with systems hands-free while working on site.

Operational and Technical Benefits
Modern Web Applications Replacing Notes Clients
Rather than performing a simple lift and shift, Migr8IT refactored and re-engineered the applications, separating tightly coupled components and transforming complex Notes functionality into clean, maintainable architectures.
Reduced Dependence on Specialist Domino Skills
Applications were rebuilt using modern web standards to improve performance, scalability, supportability, and usability while maintaining on-premise deployment to meet strict data sovereignty requirements.
Improved Usability and Long-Term Maintainability
By removing the thick-client architecture, users gained easier access to applications from modern browsers and mobile devices, while the organisation gained a platform that can evolve without reliance on legacy infrastructure.
Future-Ready Application Architecture
Applications were rebuilt using modern web standards, creating a flexible platform that can evolve as business requirements change.
The new architecture supports emerging technologies and integrations without requiring further redevelopment.
Lotus Notes Modernisation Outcomes
Reduced Dependency on Niche Skills
Re-engineering Notes applications into modern web architecture enabled long-term support by mainstream development and IT teams, removing reliance on scarce Lotus Notes expertise.
Improved Accessibility and User Experience
Staff gained secure browser-based access to applications across devices, removing dependence on the Notes client and improving speed, usability, and accessibility.
Foundation for Future Modernisation
Modern web architecture established a foundation for future platform modernisation, enabling systems to evolve without dependence on legacy Notes thick-client technologies.
Enhanced Operational Safety
Mobile, web-based access enabled staff to complete operational tasks in real time, reducing unnecessary travel across hazardous areas and improving operational safety.
Extended Lifespan of Business-Critical Applications
Instead of costly system replacement, core applications were extended with modern architecture, protecting previous investment while enabling controlled future transformation.
Faster Support and Easier Enhancement
Applications are now easier to maintain and enhance, enabling faster issue resolution, smoother upgrades, and quicker delivery of future improvements.
Experienced Lotus Notes specialists understand the hidden complexity of Domino environments. Deep technical expertise reduces risk, avoids costly mistakes, and ensures modernisation is delivered safely and sustainably.
Modernisation Frequently Asked Questions
What does 'client app to web app' migration mean for Domino?
It means converting legacy applications built for the HCL Notes client into browser-accessible web applications. The goal is to retain the underlying business logic (workflows, data, security) while delivering a modern, device-agnostic user interface and reducing reliance on thick client installations.
Can we keep all our existing business logic, agents or workflows intact during the migration?
Yes, the web platform we use contains the same design elements and constructs as Lotus Notes, and we migrate and convert all of the source code from your custom Notes application. The outcome is web-hosted apps that are almost identical to your existing apps.
Will users experience downtime or disruption when we move from Notes client apps to web apps?
Yes, but outages are brief. We build web apps in isolation meaning there is no business interruption. During the development phase, the users can continue to use the Lotus Notes apps. An outage is required prior to migration of the data, so data isn't being written as we are migrating it. We always aim to complete this outside of normal working hours where possible.
What are the benefits of moving from Notes client apps to web apps?
Benefits include accessibility from browsers and devices, reduced client-software maintenance, improved integration with modern platforms (APIs, the cloud), better user experience, and often lower total cost of ownership and future-proofing your application estate. Additionally, the web apps use open web technologies that are easier to support.
Which versions of Lotus Notes / Domino do you support for migration to web apps?
We support all versions including older Lotus Notes / Domino releases, through to the latest. We assess your version, customisations, and constraints during the discovery phase to recommend an optimal path.
How long does the migration typically take and how is it priced?
Time and cost vary significantly based on number of applications, complexity (forms, embedded logic, integrations), data volumes, and user count. Our process begins with a discovery phase (inventory + assessment) to produce a scoping document with timeline and cost estimate.
What happens to the old Notes client application once the web app is live?
Once you’ve validated the new web application and user adoption is complete, the legacy Notes client application can be decommissioned. We help you plan migration of users, archival strategy, and cut-over, ensuring compliance and traceability.
Can the migrated web app integrate with other systems (CRM, SharePoint, cloud platforms)?
Absolutely. One of the advantages of migrating to a web architecture is the ability to integrate easily with modern systems. databases, cloud services, CRM, SharePoint, APIs. This enhances the value of your application ecosystem.
How do you handle user training and support after migration?
We provide user-training sessions, documentation, and a post-go-live support plan. We ensure your teams are confident in the new web-app environment, and we offer ongoing maintenance and evolution services if you choose.
