Legacy modernisation

• The application runs on the .NET Framework and the move has been postponed several times.
• Individual components and libraries are no longer supported by their vendors.
• Business logic sits inside a monolith, so every change touches the whole system.

• Inventory of the existing code: projects, dependencies, database access, build and deployment paths.
• Migration of the application to .NET 8, including changes to ASP.NET Core and Entity Framework.
• Replacement of unsupported components with current libraries or our own implementations.
• Decoupling the monolith into separated modules or services with clear interfaces.
• Move of the application and the SQL Server database to Azure.
• Set-up of the build and release pipeline in Azure DevOps.

1. 01

   Inventory

   We read the code, talk to your developers and document dependencies and risks.

2. 02

   Target picture and stages

   We define the target architecture and cut the migration into stages that can go live individually.

3. 03

   Migration

   We migrate stage by stage, keep the application running and secure its behaviour with tests.

4. 04

   Handover

   We hand over code, pipelines and documentation to your team and support the first month of operation.

• Dependency and risk overview of the existing application
• Target architecture as a document with reasoning for each decision
• Staged migration path with effort estimates
• Migrated source code on .NET 8 in the repository
• Build and release pipelines in Azure DevOps
• Operations and handover documentation

• Fixed-price project

  Defined scope, agreed deliverables and a fixed price. Suitable when requirements and interfaces are documented.

• Time and materials

  Billing by hours worked. Suitable when scope is refined during the work or priorities change.

• Operations and maintenance retainer

  An agreed monthly hour budget for maintenance, updates and small extensions to existing applications.

• Subcontractor framework agreement

  We work as a subcontractor within another provider's project. The basis is service and work contracts, not staff leasing.
