Portfolio analysis and migration planning

This stage of assessment focuses on completing the portfolio-level discovery and analysis started in the Portfolio discovery and initial planning section. The goal is to iterate and establish a baseline for the initial portfolio of applications and infrastructure. This baseline includes identifying all dependencies, iterating rationalization models for migration, creating a detailed business case, and outlining a migration wave plan. As a result, the required data fidelity is higher. This stage will require time investment. To accelerate assessment outcomes, we recommend using as many programmatic data sources, such as discovery tooling, as possible.

Primary outcomes of this stage include the following:

• A high-fidelity application and infrastructure inventory

• A high-level migration strategy for each application

• A high-confidence migration wave plan

• A detailed business case
