Contoso migration series

We have a series of articles that demonstrate how the fictitious organization Contoso migrates its on-premises infrastructure to the Microsoft Azure cloud.

The series includes scenarios that illustrate how to set up an infrastructure migration, and how to run different types of migrations. Scenarios grow in complexity as they progress. The articles show how the Contoso company handles migration, but general instructions and pointers are provided throughout.

Migration articles

The articles in the series are summarized in the table below.

  • Each migration scenario is driven by slightly different business requirements, that determine the migration strategy.
  • For each deployment scenario, we provide information about business drivers and goals, a proposed architecture, steps to perform the migration, and recommendations for cleanup and next steps after migration is complete.
