6 strategies for migration
Rehosting Replatforming Refactoring/re-architecting Repurchasing Retaining Retiring
Rehosting
Also known as “lift-and-shift” involves moving applications without changes.
Replatforming
Also known as “lift, tinker and shift”.
o Involves making few cloud optimisations to realise tangible benefit.
o Optimisation achieved without changing core architecture of application.
Refactoring/re-architecting
o Involves reimagining how application is architected and developed by using cloud-native features.
o Driven by strong business need to add features, scale or performance that would be difficult to achieve in application’s existing environment.
Repurchasing
o Moving from traditional license to software-as-a-service model.
o E.g. migrating from customer relationship management (CRM) system to Salesforce.com
Retaining
o Keeping applications that are critical for business in source environment.
o Might include applications that require major refactoring before they can be migrated or work postponed until later time.
Retiring
Process of removing applications no longer needed
