Application Modernisation by OpenSky

Using AI to accelerate the assessment and modernisation pathways, we significantly reduce the cost and labour that would otherwise be required for a manual application modernisation project. Post modernisation, our approach empowers teams to deploy, operate and maintain existing applications more efficiently and cost effectively. Whether legacy .NET, Lotus Notes or Access/Excel databases, we offer modernisation options to secure and optimise these applications for your business.

.NET Application Modernisation

Whether re-platform, re-factor or re-host, we have the expertise and experience to provide the right solution to modernise your existing .NET applications to future proof and secure for years to come. Certified by Microsoft for the “Migrate Enterprise Applications to Microsoft Azure Specialisation”, we have successfully modernise business critical .NET applications, making them more agile and responsive.


  • Re-platforming: This approach involves adapting and optimising your application to better utilise cloud capabilities, significantly enhancing its scalability and performance. It's ideal for businesses seeking to modernise their applications without extensive redevelopment, while also integrating modern cloud services.
  • Re-hosting: Often referred to as "lift and shift," this strategy entails moving existing applications to the cloud with minimal modifications, providing a straightforward path to cloud adoption. It is a quick, cost-effective solution that reduces infrastructure overhead and sets the stage for further cloud-based innovations.
  • Refactoring: This method requires re-architecting and potentially rewriting parts of the application to fully exploit cloud-native features, aiming for maximum efficiency and scalability. It's the most comprehensive form of modernisation, offering long-term benefits like increased agility, improved performance, and reduced long-term maintenance costs.

The transition to a Low Code platform from traditional systems like Lotus Notes, Microsoft Access, and Excel is not just a technical upgrade; it represents a strategic move towards a more agile, secure, and efficient data management system. This transition supports the digital transformation goals of the organisation by fostering a more collaborative, productive, and secure work environment.

Enhanced Security and Resilience Standards

  • Robust Data Protection: Transitioning to a Low Code platform ensures that your databases are protected with the latest security measures, reducing the risk of data breaches and unauthorized access which is paramount for CIOs overseeing enterprise data security.
  • Compliance with Regulations: Modern Low Code solutions are often designed to comply with various data protection regulations, which is critical for organizations handling sensitive information and aiming to avoid legal and financial penalties.
  • Improved Resilience: Low Code platforms offer better resilience against system failures, ensuring data integrity and continuity of business operations, a vital concern for any enterprise-level organization.

Empowering Multi-User Access

  • Collaboration and Accessibility: By modernising to Low Code platforms, organisations can enhance collaboration, as these platforms are inherently designed for multi-user access, allowing simultaneous inputs and real-time data sharing.
  • Scalability: Low Code solutions can easily scale to accommodate growing user bases and increasing data volumes, making them ideal for expanding organisations.
  • Centralised Control and Management: For a CIO, centralized control is crucial. Low Code platforms offer a unified view and control over multiple databases, simplifying management and oversight.

Advanced User Experience to Drive Productivity

  • Intuitive Interfaces: Low Code platforms typically feature user-friendly interfaces, making it easier for non-technical users to navigate and use the system effectively, thereby reducing training time and costs.
  • Automation of Routine Tasks: Automating routine tasks with Low Code solutions can significantly enhance productivity, allowing staff to focus on more strategic tasks.
  • Customisation and Flexibility: These platforms provide the flexibility to customise applications as per business needs, which is particularly beneficial for organisations with unique operational workflows.
