Detailed portfolio discovery
This is where you start to pull the pieces together and develop a strategy for migration. At this stage, you want to consider where your cloud journey fits into your organization’s larger business strategy and find opportunities for alignment of vision. A well-aligned migration strategy with a supporting business case and a thorough application migration plan sets the proper groundwork for cloud adoption success.
A critical aspect of your migration strategy is the collection of application portfolio data and rationalization of this data against the seven Rs of migration: rehost, replatform, refactor/re-architect, repurchase, relocate, retire, and retain. You build a migration wave plan by using the seven Rs to categorize what is in your environment. Next, blend those categories with information about interdependencies, technical complexity to migrate, and how you will migrate each application or set of applications. After you analyze your applications according to the seven Rs, you can outline a migration plan for each application in your portfolio. This is an iterative plan that will mature as you progress through the migration, build confidence, learn new capabilities, and better understand your existing estate.
