Continuing from Part 1, this blog dives into the final steps and additional critical considerations for migrating from a commercial cloud to GCC High cloud. With proper preparation from the first half, you’re now ready to address advanced considerations that ensure compliance, seamless operations, and user adoption.
- Approve a List of Non-Migrated Accounts, Groups, and Mailboxes
Not all entities need to be migrated to GCC High. Dormant accounts, outdated distribution lists, or inactive mailboxes might no longer be relevant and can be left behind. Compile a list of these entities and share it with the customer for review.
Once finalized, archive any important data externally for potential future reference. This step not only declutters the new tenant but also reduces both cost and complexity during migration.
Pro Tip: Use this opportunity to update your directory services and remove obsolete records for better tenant hygiene.
- Migrate Archive Mailboxes
Archive mailboxes often contain critical historical data that may be essential for business continuity. The migration of archive mailboxes typically requires additional tools and extended timelines, given the data size and complexity.
Ensure archive mailboxes are included early in the migration plan with appropriate testing. Work with your customer to prioritize high-importance archive mailboxes that may need expedited processing.
Important Note: Follow up with users post-migration to confirm no data is missing and that archives are fully accessible.
- Provide Training and Guides for Mobile Email Configuration
After migration, users will need to reconfigure email on their mobile devices to align with new DNS settings and authentication protocols. A communication plan backed by user training is critical for minimizing disruptions.
Prepare easy-to-follow guides that cover both iOS and Android devices. Host training sessions to walk users through the process and troubleshoot common issues. The goal is to empower employees with self-sufficiency while reducing IT helpdesk tickets.
Best Practice: Include visual aids, such as screenshots and videos, to make guides as user-friendly as possible.
- Additional Considerations for a Smooth Migration
The complexity of a GCC High migration extends beyond the immediate considerations covered so far. Here are a few more critical elements to ensure success:
- Testing: Conduct rigorous pre- and post-migration tests to confirm data integrity and service functionality. This includes validating connectivity, permissions, and shared resource access across the organization.
- Security and Compliance: Review and apply GCC High’s enhanced security measures, such as stricter DLP policies, multifactor authentication, and encryption protocols.
- Third-Party Tools: Test all third-party integrations tied to the commercial tenant, confirming their compatibility in GCC High.
- Change Management: Communicate openly about the migration’s purpose and expected outcomes. Employees are more likely to adapt when they feel informed and supported throughout the process.
Final Thoughts
Transitioning to GCC High cloud is no small task, but it is a necessary one for organizations that must meet stringent compliance requirements. By addressing these nine considerations, split across both parts of this guide, you can approach the migration with confidence and a well-rounded strategy. With a focus on continual testing, employee alignment, and attention to detail, your organization can enjoy a seamless transition into this compliant, secure cloud environment.
