Each acquisition introduces new users, identities, mailboxes, collaboration platforms, and business data that must be incorporated into the acquiring organization’s technology environment without disrupting business operations. A global data and analytics company had acquired a small business and needed to rapidly integrate approximately 28 users and their Microsoft 365 data into its existing environment. The migration included user mailboxes, shared mailboxes, OneDrive content, SharePoint sites, and Microsoft Teams data. With competing priorities across the business and limited internal bandwidth, the organization wanted a trusted partner that could accelerate the integration while minimizing risk and disruption. Having successfully partnered with Concurrency on previous acquisition-related migrations, the company turned to an established migration approach that could help move users and business data into its Microsoft 365 tenant quickly and efficiently. Customer Profile A global market research and data analytics organization that continues to expand through strategic acquisitions. As part of its growth strategy, the company regularly integrates acquired businesses, employees, and technology environments into its enterprise Microsoft 365 platform to provide a consistent and secure employee experience. Key Problem Following an acquisition, the organization needed to migrate users and collaboration data from the acquired company’s Microsoft 365 environment into its own tenant. The project required careful planning, migration expertise, and coordination across stakeholders to ensure business continuity while transitioning mailboxes, identities, files, and collaboration services. With other strategic priorities competing for attention, leadership chose to leverage an existing partnership with Concurrency to accelerate the migration and reduce the burden on internal teams. BUSINESS CHALLENGES Limited Internal Capacity While the organization had experience managing acquisitions, internal teams were balancing multiple priorities across the business. The migration required specialized Microsoft 365 knowledge, project coordination, and technical execution that would have placed additional strain on internal resources. Complex Microsoft 365 Migration Requirements The migration included multiple workloads, including Exchange mailboxes, OneDrive content, SharePoint sites, Microsoft Teams, and user identities. Each workload required validation, testing, and coordination to ensure a successful transition. Accelerated Integration Timeline Leadership wanted to quickly absorb the acquired organization and provide users with a stable operating environment. Success required a repeatable migration strategy that balanced speed, business continuity, and risk management. Outcomes Faster Post-Acquisition Integration The organization established a structured approach for migrating acquired users and Microsoft 365 workloads into its enterprise environment. By leveraging a proven migration methodology and existing partnership, the company accelerated integration activities while reducing pressure on internal resources. Unified Microsoft 365 Environment Users, mailboxes, files, and collaboration services were transitioned into a common Microsoft 365 platform, helping create a consistent employee experience and reducing the complexity of managing separate environments following the acquisition.
