Post-Migration Checklist: What to Do After Moving to GCC High
Blog Article
You’ve completed your GCC High migration—but the journey doesn’t end there. Many organizations overlook critical post-migration steps that impact compliance, performance, and user adoption. A smooth transition is only successful if the environment is secure, monitored, and embraced by users.
In this article, we walk through the key actions every organization should take after moving to GCC High, and how GCC High migration services can help ensure long-term success.
1. Validate Security Configurations
After migration:
Review Multi-Factor Authentication (MFA) enforcement
Test Conditional Access and Intune device compliance rules
Confirm encryption settings on data at rest and in transit
✅ Don’t assume security settings carried over—validate them.
2. Conduct a Post-Migration Audit
Use tools like Microsoft Purview and Compliance Manager to:
Check for any unprotected data or legacy permissions
Run a NIST 800-171 gap analysis
Document your compliance posture for audit readiness
✅ This provides a baseline for future improvements.
3. Train Users on the New Environment
Even if they used commercial Microsoft 365, GCC High has differences:
Restricted collaboration features
New workflows for document sharing and Teams usage
CUI handling responsibilities
✅ Conduct live training and provide guides tailored to your environment.
4. Monitor Performance and Adoption Metrics
Track how users interact with:
Teams, SharePoint, and Exchange Online
Device compliance rates in Intune
Login and authentication behavior via Azure AD logs
✅ Identify issues early and improve user experience while maintaining compliance.
5. Establish Ongoing Governance Processes
Post-migration success depends on sustainability. Set up:
Regular access reviews and permission audits
Change management protocols for compliance-impacting updates
Incident response simulations and policy refreshes
✅ GCC High migration services often include post-migration governance planning to keep you compliant over time.
