Operating in a complex and highly distributed environment within a regulated industry involves managing the lifecycle of vast amounts of documentation. The design, construction, operation and decommissioning of an oil & gas offshore production platform alone is a decades-long process, during which many millions of documents and huge amounts of data are created and must be retained. After transitioning to Microsoft 365 and the Azure cloud, this organization wanted to decommission their on-premises SharePoint servers and move the contents to their Azure cloud. The content had to be indexed and searchable so, should regulators request specific information, they can quickly and easily produce it. They migrated 15TB of data from one data center and plan to migrate more data from other centers in phases.
