GCC/GCC High Migration Service for Government Contractors

About Microsoft GCC & GCC High

Microsoft GCC and GCC High are secure, government-specific versions of Microsoft 365 designed to meet U.S. compliance standards, with GCC High offering stricter protections for defense and regulated data.

These environments can satisfy a significant portion of compliance requirements for the Department of Defense Security Requirements Guidelines such as CMMC, Defense Federal Acquisition Regulations Supplement (DFARS), and International Traffic in Arms Regulations (ITAR).

Office 365 Government plans are monthly subscriptions and can be licensed to an unlimited number of users.

About Our GCC/GCC High Enclaves

At SysArc, we don’t push you into a pre-configured solution and hope it fits. Every enclave we build, every migration we run, and every GCC High environment we stand up is 100% tailored to your unique data flows, user communities, and security posture. The result? An environment that actually feels like it was built for you — because it was.

GCC/GCC High Migration Process

SysArc performs a pre-staged cutover migration approach which replicates the existing environment to the new GCC/GCC High space and only during a designated cutover window will services be moved into GCC/GCC High. This allows verification that all data is replicated to the satisfaction of our customers prior to any business impact occurring during a cutover weekend.

Migrations from the Following:

• Tenant to Tenant (Commercial to GCC/GCC High) to include:
  • Exchange Online
  • SharePoint Online
  • MS Teams
  • OneDrive
• On-prem Exchange to GCC/GCC High
• On-prem SharePoint to GCC/GCC High
• Google Workspace (formally GSuite) to GCC/GCC High (Email, Drive, etc.)
• Legacy POP/IMAP email to GCC/GCC High

Migrating into a Dedicated “Enclave” in GCC/GCC High:

• Custom Enclave Builds: Fully custom architectures designed to align precisely with your unique classification boundaries and mission requirements.
• Preserved Workflows: Migration strategies engineered to preserve your existing processes instead of forcing your team to change them.
• Exact Engineering: Environments built to your exact security, performance, and workflow needs — never “close enough.
• Future-Ready Architecture: Designed with your company’s growth and an evolving compliance landscape in mind.
