Modernise Legacy Applications
Modernising critical systems with Microsoft Business Applications & AI.
When existing systems need to evolve
Many of the systems that underpin your service delivery and operations remain critical to how your organisation functions.
They still hold essential data, support complex workflows and enable day-to-day decision making. Modernisation needs to improve capability without increasing risk, while aligning with security, governance and compliance expectations.
Modernise Legacy Applications is The Factor’s approach to helping organisations assess, evolve and replace legacy systems using Microsoft Business Applications and AI, in a way that is deliberate, defensible and built to last.
What modernisation delivers for you
Modernisation is designed to improve capability while preserving what already works.
Through this service, you are supported to:
- extend the life and value of existing systems
- improve usability, accessibility and integration
- introduce automation and intelligence where it adds value
- reduce complexity across applications and processes
- strengthen alignment with modern governance and security expectations
The Factor solution
Factor approaches modernisation as a staged, platform led evolution grounded in Microsoft technology.
We assess, modernise and replace legacy applications incrementally using Power Platform, Dynamics 365 and AI capabilities, integrating with existing systems and data where required.
This approach reduces disruption, supports decision making and enables progress at a controlled pace.
Application assessments to evaluate current systems
We begin by working with you to understand your current application landscape and identify where modernisation will deliver the greatest impact.
The focus is on building a clear view of what exists today, what is fit for purpose and where change will reduce operational or security risk.
This includes assessing:
- business critical systems and workflows
- usability and accessibility constraints
- integration and data dependencies
- areas of manual effort or duplication
The outcome is a prioritised view of modernisation opportunities that supports confident next steps.
Migrate and upgrade using Microsoft platforms
Using Microsoft Business Applications, we modernise functionality incrementally, so each change fits within your existing operating and governance models.
This may include:
- migrating or rebuilding interfaces using Power Apps
- upgrading services to Dynamics 365 where appropriate
- automating workflows with Power Automate
- introducing structured data, reporting and visibility
- embedding AI capabilities where they deliver practical benefit
Each upgrade is designed to reduce technical debt while improving reliability and usability.
Form-enabled workflow and case management integration
Where processes rely on forms, approvals or case based workflows, we apply form-enabled workflow and case management best practices to improve integration and flow across systems.
This includes using proven Microsoft patterns and products to:
- streamline data capture and validation
- integrate workflows across platforms
- reduce manual handling and rework
- improve visibility across cases and processes
These patterns allow modernised applications to integrate cleanly with other systems while supporting secure, end to end process execution.
Aligning modernisation to governance and operations
Modernisation in regulated environments must align with established controls.
We ensure modernised applications:
- align with security, identity and access models
- meet data protection and compliance requirements
- integrate cleanly with existing platforms
- are designed for long term operation and support
This ensures modernisation improves capability without introducing new operational or security risks.
