The client was performing a planned migration from an on-premise mixed environment of Microsoft Exchange 2010 and Lotus Domino 9 to a completely hosted Office 365 environment.  The volume of mail objects were 2000+, including user mailboxes, shared mailboxes, group mailboxes, shared calendars and resources.

Primary objective was to perform a clean cut-over migration to the Office 365 platform during a weekend maintenance window. All mailboxes were required to be migrated, synchronized and fully accessible with offline local archives brought into the cloud platform.  Distribution groups were to be migrated to Office 365 Groups, contacts were to be cleaned up and imported, and consolidated resource management (meeting rooms, projectors, etc.) was to be introduced.

Secondary objective was the implementation and roll-out of the Skype for Business platform to support the enablement of online real-time communication collaboration.

The primary challenge involved reactive changes to the planned Office 365 architecture and deployment, from a large quantity of unknown’s due to internal staff churn, and changing requirements/project scope.  We maintained timelines and velocity with daily stand-up meetings, open collaboration and granular allocation of tasks and duties with various team members.

The secondary challenge met was the migration of Lotus Domino mailboxes into Office365, requiring a 3rd party tool, BitTitan, to complete the process.  The tool involved a small amount of complexity, and required comprehensive testing and planning to ensure fluid data transition.
