Microsoft 365 GCC & GCC High Migrations

ITAR data and certain CUI categories effectively require Microsoft 365 GCC High — a separate, U.S.-sovereign cloud with its own licensing, its own identity boundary, and real migration complexity. Many providers talk about GCC High; far fewer have moved a live business into it.

We've done the hands-on work, including cross-cloud collaboration between commercial and GCC High tenants — one of the trickiest scenarios in the Microsoft ecosystem. We map your data first, confirm whether you actually need GCC High (many contractors don't), and execute the migration with minimal disruption.
