Pre-Migration Phase
Introduction
Nathan is the Lead Architect for the migration project at AD-Financial. Nathan is concerned about the complexities and risks of migrating large production workloads and has been comparing the strategies, practices, and tools that have proven their value, leading to a successful migration.
There are as many reasons to move to the cloud as companies out there and, at one point, those companies will have to decide on a cloud-migration posture. Every company’s motivation, constraints and goals to move to the cloud are different hence each cloud migration journey is unique. That uniqueness grants the need for a careful planning of the cloud migration during the Pre-Migration Phase.
In the Pre-Migration Phase you need to define:
| Why are you migrating ? | |
| What is changing ? | |
| How do you deliver ? | |
| Observability scope ? |
Once the Why, What, How and Observability Scope questions have been answered then those responses need to be transformed/implemented into the changes that need to be introduced to the production environment and supporting systems (this means that the needed configuration, coding, tooling and so forth has to be completed and tested before moving to the Migration Phase) The more effort you put on rigorously completing the Pre-Migration Phase the more successfull and smooth transition to the cloud you experience.

Let’s dive in to the details of the Why, What, How, and Observability Scope for the migration.
