Seamless transition from complex global environment ensures business-as-usual in facilities service divestment.

Client: Empact Group (ex Compass)


  • Global operations in over 50 countries
  • 1,500 employees widely distributed over 30,000 client locations
  • Migration and amalgamation of three domains, systems not running optimal operating system versions and 13 historic businesses’ email traffic
  • Co-existence required from day one


  • New, independent Microsoft 365 tenancy
  • Seamless tenant-to-tenant migration, minimising disruption
  • Delivered ahead of deadline, resulting in licence cost-savings

The challenge

One of the largest food services and facilities companies in the world, operating in over 50 countries and providing services in over 30,000 client locations, Compass Group Southern Africa shareholding was acquired by Thebe Investment Corporation (Pty) Ltd (TIC) in March 2019. The resulting company, Empact Group, needed to create its own independent IT environment with no negative impact on its workforce from day one of operations. Our prime goal was to ensure business as usual for all Empact employees and customers. There needed to be minimal user input because the business is widely distributed with many staff working on site across 30,000 client locations. There were also significant time constraints on the migration. Compass Group had three domains to migrate and a number of systems that were not running the optimal operating system version. In addition, there were 13 separate historic businesses that had to be accounted for, when supporting email traffic from the long-standing customer base.

“The services we provide mean our business is pretty much a 24 x 7 operation, so any break or downtime in key line of business systems as we migrated would not have been acceptable”

Our solution

We’re proudly vendor agnostic and scope out every project with our clients, before selecting an approach that suits their commercial needs. In this instance, we identified Binary Tree as our optimal partner for both the migration of the Outlook email and OneDrive for Business workloads, as well as for transitioning vital infrastructure.

Disruption-free business as usual

The migration was phased to take place over the course of several months. In order to minimse disruption to the business we established co-existence from day one with fault-free email exchange, meeting scheduling and document-sharing between all staff, regardless of whether they had already been moved to the new Empact Group Office 365 tenant, or were still part of the main domain. Throughout the migration process, BinaryTree’s ability to keep email addresses and calendars in sync meant staff could continue to work without disruption and, using address re-writing services, the outside world could still contact them using the legacy email addresses, any of the previously acquired company email addresses or the new identity.

Seamless, user-friendly experience

In order to ensure that staff had immediate access to all their regular resources and applications after they had logged into the new environment, we created a new Active Directory (AD) service into which all existing user profiles, servers and other objects needed to be migrated. This ensured that it did not appear to staff as though they were brand new users; an important component in ensuring staff remained happy and able to get on with their day-to-day tasks. Binary Tree’s AD Pro solution allowed the AD migration to take place seamlessly and enabled all three domains to be migrated from one central console.

Coping with complexity

Once the new AD had been commissioned, the process of getting servers and client systems to switch across also proved to be a challenge owing to a mix of older platforms and a highly distributed workforce.

“For platforms running older operating systems, even though the software could not do a full migration, we were able to use certain functionality to assist in making the manual cutover process to the new AD server easier. AD Pro also allowed users to move across to the new network without being in the office.”
Cloud Essentials migration to cloud


Highly efficient project completed ahead of deadlines and delivering unexpected cost savings

Cloud Essentials project managed a seamless migration, surpassing timeline expectations and therefore reducing overall costs because only one month of Microsoft licence overlap was required.

Daily updates for the IT team and a weekly summary for other key stakeholders ensured that Empact Group were kept up to date on the progress of the migration as it evolved. Our end-to-end project management team also supported the switch over of various servers that were still residing on-premises. These hosted other critical line of business applications, including business intelligence and analytics systems, payroll application and staff training platform. Over time the Group’s intention is to cloudify these servers and introduce other new technologies that will help streamline its business and enhance customer service.
