Client: One of the world’s largest fintech companies
In 2017, two global fintech companies merged. These two companies were in separate Office 365 tenants and required migration into one tenant. At the time, this migration was one of the largest in Europe. As part of our client’s strategy to enhance their global presence in the US, they also acquired another company and required their Office 365 tenant to be migrated as well. These migrations presented a number of complexities, not least the global distribution of a large number of users (over 16,000), the amount of data and distribution of the data across the businesses and the requirement to migrate from 12 Office 365 domains into one single domain.
Cloud Essentials were chosen for this tenant to tenant migration project because of our experience dealing with complexity. The client had a vast environment with a lot of on-premises servers. We were chosen because we were able to build a plan around all of it. We provided the client with end-to-end support throughout the migration, starting with a detailed security baseline assessment and scoping, expert planning and migration design by our cloud architects and step-by-step management of the migration process. This was all overseen by an experienced project manager who provided clear communications with all stakeholders at every stage.
We’re vendor agnostic, so having scoped out the project in detail, we were able to advise our client on the best tools to meet their specific migration challenges. Our expert cloud architects recommended using Binary Tree Power 365 and Binary Tree Express for the migration of mailboxes and ShareGate for the migration of SharePoint, Teams and OneDrive for business. EmPass was used for to achieve bi-directional password synchronisation.
Despite the client using our solutions and professional services for their project they did have the technical capacity and capability of managing the project once the preliminary stages and testing had been completed. Therefore, in order to keep costs lower, they opted for a hand over migration service which Cloud Essentials was able to provide. This tenant to tenant migration required co-existence and a phased approach which Cloud Essentials were also able to achieve.
We’re experts in tenant to tenant migration. Our experienced cloud architects employed their knowledge of similar challenges to ensure that a realistic, thorough implementation plan was drawn up and executed. We helped our client overcome the challenges that the migration brought throughout the hand over period and provided them with a safe and secure migration service.
