Iterating the 6 Rs migration strategy selection

At this stage, we recommend that you iterate and evolve the 6 Rs decision tree. The Determining the R type for migration section introduced a default decision tree. We recommend revising the tree, considering the learnings throughout migration of the initial pilot applications, and ensuring that it still aligns to business drivers, prioritization criteria, and your unique circumstances. Validate the decision tree with sample applications, and verify that it still produces the expected strategy. Otherwise, update the logic accordingly. The resulting tree will be key in establishing baselines for the portfolio of applications and in allocating migration strategies for each application component.

Make sure that migration strategies are allocated to each application component and its associated infrastructure. This information is a key factor when estimating effort, capacity, and skills needed, and when creating migration wave plans.
