Case Study: Large Government Agency achieves faster, lower-cost Office 365 migration with Commvault

Large Government Agency - Customer Case Study

A large government agency, supported by a leading enterprise services vendor, needed to migrate more than 200,000 email users and 165 TB of files from Exchange 2010 to Office 365 while reducing upfront and ongoing costs, minimizing IT burden, and preserving user access, compliance and governance during the move.

Commvault archived data older than six months before migration to shrink the data footprint, kept archived content searchable and accessible via Explorer and Outlook plug‑ins, the web console or standard IMAP clients, and provided options for ongoing archiving and records retention. The approach accelerated the migration, lowered total cost of ownership, maintained end‑user access and compliance capabilities, and encouraged the vendor to expand similar projects across other government clients.
