51 Terabytes, Zero Escalations A Major Utility Company's Seamless Move to SharePoint

A leading Australian utility company faced a strategic turning point in its IT landscape. With costly OpenText licenses expiring and a long-term strategy to standardize on Microsoft 365, the organization decided to migrate its vast enterprise content to SharePoint.

The project was not just about cutting costs; it was about ensuring business continuity across dozens of departments while preparing for a more agile, cloud-based future. In total, the utility company needed to transfer nearly 51 terabytes of content: around 25.5 million documents spread across more than 30 business functions.

The transition from OpenText Content Server to Microsoft SharePoint was divided into seven releases over the course of a year. To maintain continuity with business-critical applications, Xillio also deployed its Link Redirection Service, ensuring that existing OpenText URLs would continue to function in the new environment.
