Case Study
Celtic Utilities Group
Excellence IT successfully merged the IT systems of three companies into one unified structure. By combining Microsoft 365 accounts, servers, and other systems, we streamlined their operations and improved efficiency.
This case study showcases how we handle mergers, acquisitions, and name changes, ensuring smooth and effective integration of accounts and data.
The Challenge
The primary challenge was to merge the three distinct companies, each with their own Microsoft 365 tenancy, servers, and systems, into one. This included migrating user accounts, mailboxes, OneDrive data, SharePoint data, and devices enrolled in Intune. Additionally, we had to consolidate server data, including the Microsoft SQL Server line of business applications and systems, into one central instance.
The Solution
To address these challenges, we utilised the Quest On Demand Migration tool, which we are certified to use. This tool allowed us to automate the migration of enrolled devices from one tenancy to another, saving hundreds of hours. We successfully migrated around 100 devices from three different tenancies into one central tenancy, all while ensuring data protection controls and security remained intact during the migration process.
The Results
All devices are now centrally managed, and all data is consolidated into one instance of each system. This has streamlined operations and improved efficiency across the newly formed company. The Quest On Demand Migration tool was instrumental in achieving these results, allowing us to complete the migration process promptly and efficiently.
Here’s what Lesley, Director of Administration, had to say about the tool and process:
“Excellence IT facilitated the mammoth task of merging IT systems across our 3 businesses. The project was enormously complex as it including migrating all our devices, on-premise and cloud infrastructure, as well as applications and data into the new group business. A team from Excellence IT scoped and delivered on the project enabling great efficiencies for our companies that will continue to bear fruit for years to come.”
