Migrate & Modernise – Accelerate transformation at scale

Both migration and modernisation patterns are important to achieving cloud benefits. Migration is best to quickly realise the value of cloud, while modernisation is best for differentiating the value of distinct apps. 

Migration strategy decision criteria are based on both business and technical aspects, for While organisations choose to migrate to quickly realise the value of cloud, other times modernisation will help them differentiate the value of distinct apps. Appropriate strategies – such as refactoring, re-platforming and retiring – are applied for each application.  

Our toolset: Workload & Data Migration, Validation.
