Building for independence: how Deneys and SoftwareOne delivered a complex technology transition in three months

A year of work and three months to do it

When Deneys prepared to return to independence in South Africa, it faced one of the most complex technology challenges a professional services firm can undertake. Systems, applications, user devices and Microsoft 365 services had to be separated from a shared international environment and transferred to a new Microsoft tenant in South Africa without compromising security, disrupting client work, or affecting the systems of the international network the firm was leaving.

Deneys fixed the completion date at March 31, 2026. Maurae Wooding, chief information officer at Deneys, advised the board that a program of this complexity would ordinarily take a year. With December largely unavailable because of South Africa's summer holiday, the effective delivery window was January through March.

“A year of work, three months to do it, and a date that could not move,” says Wooding. “That framed every decision we made from that point on.”

Deneys needed a partner that understood its environment and had delivered tenant separations at speed. SoftwareOne had already supported the firm with an Azure workload migration and its Microsoft Copilot program. Wooding combined that firsthand experience with research into SoftwareOne's international delivery record before recommending the company to the CEO and CFO.

A migration with no room for error

The program separated Deneys' Microsoft environment from the shared international estate. Identities, Microsoft 365 services, security policies, devices, applications, collaboration environments, mailboxes, document repositories and licensing all had to move while lawyers and support staff continued serving clients. Every decision also had to protect the systems remaining with the international network.

“This was never simply moving from one tenant to another,” says Wooding. “We were building an entirely new environment for ourselves while making sure the organization we were leaving was not affected. Both of those things had to be true at the same time.”

Deneys set the architecture principles, maintained the deadline and retained responsibility for client risk. SoftwareOne supplied delivery capacity and specialist expertise. Within weeks, the teams were operating as one.

When platform permissions arrived nearly two weeks late, the team reorganized the plan, moved all work that could be completed forward and protected the critical path. Frequent planning sessions tracked every dependency through to cutover.

“There was no flexibility in the timeline,” says Wooding. “March 31 was not moving.”

Over the weekend before the deadline, months of preparation converged in a single coordinated cutover. At 4:00 p.m. on Friday, March 27, more than 400 devices were collected to be rebuilt and reconnected. Everyone needed access by Monday, March 30 (or by Sunday for lawyers with court appearances) to use email, retrieve documents, collaborate and serve clients.

Applications were repackaged for the new tenant, devices were moved into the new management environment and mobile application management was implemented. SoftwareOne helped Deneys choose approaches that could be delivered in the available window.

“That mattered most on mobile management,” Wooding says. “My team had used a device-level approach in the previous environment and wanted to keep it. It took patience and real technical credibility to persuade us that an application-level approach was the right call for this window. It was.”

Device returns were staggered, with court appearances and urgent commitments prioritized. SoftwareOne remained closely involved, resolving user issues and completing lower-priority back-end work after staff were working again. At midnight on March 30, deneys.co.za went live.
