Consolidating Azure Deployments During M&A

• Azure deployments under different Azure Active Directory tenancies resulting from mergers and acquisitions should be consolidated under a single tenancy.
• The difficulties and risks of consolidation may be best handled with the assistance of an external consulting partner.

Mergers and acquisitions (M&A) are a regular occurrence for some organizations. M&A can result in the existence of multiple Azure Active Directory (AAD) tenancies within an organization, and more than one of these tenancies may have an Azure deployment (that is, different Azure subscriptions may be linked to different tenancies). Organizations should pursue consolidation of such deployments. However, the processes involved could be complex, so organizations that rarely engage in M&A may find it more cost effective to use an external consulting partner rather than developing processes they are not likely to reuse.

This report focuses on the consolidation of multiple Azure deployments that were created under different AAD tenancies. There are other Azure deployment considerations and opportunities that could arise during M&A that are not addressed in this report.
