UK and International Migration to a Unified Collaboration Platform


  • The client had separate tenants in each territory which was causing disparities for the teams. The tenants were not joined up and instead were acting as a “group”.
  • Standardisation was required owing to different configurations and management strategies for each territory.
  • The client had been using a particular platform for a number of years, however it had reached its limit in terms of capabilities and so the client needed an alternative.
  • The client also needed support with enhancing governance and security.


The 848 Group delivered a large scale migration project, moving one of the largest cinema operators in Europe and the UK to a unified collaboration platform. The client welcomes more than 100 million guests each year to enjoy great hospitality whilst watching the latest films and entertainment in over 350 cinemas with 2,700 screens in the UK, and a total of 1,000 theatres and 11,000 screens across the globe.

The client had a disjointed infrastructure spanning its international territories which was causing a range of issues regarding collaboration and efficiency.

The Challenge.

Operating over 5 countries with 5 separate tenancies, the client was reaching the limits of being able to operate effectively and securely as a single entity. Given there were multiple tenants, users were working with what was an inherently challenging identity environment. Some of the challenges being encountered were that:

  • Employees were being forced to share documents across tenants which was causing difficulties.
  • Sharing of documents became convoluted, it became difficult to track ownership of digital assets.
  • Collaboration between colleagues in different territories was unproductive.

Technical capabilities were being reached in what could be achieved in the existing ecosystem, with colleagues needing to find alternate tooling to accommodate standard line of business processes.

The Solution.

848 undertook a detailed discovery exercise to understand the usage of the existing platform and the organisations current ways of working. This ensured a suitable productivity platform could be implemented to accommodate the clients needs.

The cinema group was an existing client of Deloitte. 848 has been a key collaborator of Deloitte for over 6 years. 848 worked with Deloitte to devise a migration plan, moving from 5 separate workspace tenants, including mail, personal, data and shared data, to a cloud-first unified collaboration tenant.

Based on the user personas identified, 848 developed an appropriate license model for each use case, from frontline cinema hosts to office-based colleagues.

Being cognisant that the user community had been accustomed to a particular way of working for over 5 years, 848 set out to support a company-wide training plan, to enable colleagues to easily transition to and adopt the new cloud workplace.

848 worked with the client to develop a phased rollout to smoothly transition from 5 workspace platforms to a single, unified collaboration environment. This included migrating the client from their existing mail platform to a new online email solution and migrating both personal and shared from the old drive to a new shared business drive.

The 848 team also migrated sharing links, enabling users to retain the shared links, causing minimal disruption to business processes. 848 also provided training to users on the differences between the platforms.

The Result.

The client was left with a standardised, group-wide productivity and collaboration platform. This has not only enabled employees to collaborate with colleagues effectively and securely across the entire group, but also with designated external parties – a capability that was absent in the previous tenants.

The client now has access to a secure, centrally managed collaborative environment, whereby colleagues are significantly more effective when working with users within, and outside of the business.

Users have access to Data Loss Prevention and Sensitivity Label capabilities, ensuring data is handled by only those for which it is intended. The IT teams have the visibility of the estate to effectively assure the business of the integrity of their data, with an overall reduction in total cost of ownership. The clients’ security teams have the visibility to real time and historic events, giving them insight to activities that they were previously unable to quantify.

The secure collaboration platform has improved connectivity, efficiency and communication across all territories.
