Mergers and Divestures are strategic directions of organizations for business reasons which have considerable impact on their exiting IT and user workloads. Office 365 (O365) as the preferred modern workplace platform for global corporates is not immune and requires significant investment. Care should be taken to ensure that there are no user disruptions, loss of content and communication (especially legal/compliance/auditory) and zero loss to operating business. As O365 is primarily integrated with the organization’s on-premise Active Directory, any transformation activity resulting from merger or divesture involves multiple teams (infra, O365, Security, procurement, management, compliance/risk) and a well-thought-out approach. The objective of this white paper is not to provide a comprehensive solution for the entire transformation process (since it is case specific) but to touch upon key aspects from an O365 perspective for important scenarios.
Key scenarios, Solutions
Below, we will highlight a couple of common scenarios and provide a perspective of the potential way forward. Do note that any O365 solution needs AD and a security solution/mechanism to be implemented first which is not considered. Every customer case will need to be validated per its own specification, but the example scenarios are meant as a guidance and can be used as a stepping stone for further understanding.
Scenario 1: Merger: Company-A is merging into Company-B wherein both the entities have their own sets of Active Directory (forest and domains), applications with a single Office 365(O365) tenant present in Company-A.
