Question 3

List the 6 Strategies for Migration

Answer 3

1) Rehosting
* Lift and shift
* Move applications without changes
2) Replatforming
* Lift, tinker and shift
* Make a few cloud optimizations to realize a tangible benefit
* Optimization is achieved without changing the core architecture of the application
3) Refactoring /re-architecting
* Reimagine how an application is architected and developed by using cloud-native features
* Driven by a strong business need to add features, scale or performance that would otherwise be difficult to achieve in the applications existing environment
4) Repurchasing
* Move from a traditional license to a software-as-a-service model (CRM to Saleforce)
5) Retaining
* Keep applications that are critical for the business in the source environment
* Might include applications that require major refactoring before they can be migrated or work that can be postponed until a later time
6) Retiring
* Remove applications that are no longer needed
