Migration Process
Preparation Phase
1. Assessment and Planning
Inventory: Begin by taking stock of your current on-premises Exchange environment. Identify mailboxes, distribution lists, public folders, and other key components.
Dependencies: Understand the interdependencies between Exchange and other systems, such as Active Directory, DNS, and antivirus solutions.
Compatibility: Ensure that your on-premises environment meets the prerequisites for migration, including supported versions of Exchange Server and client applications.
Migration Scope: Determine what needs to be migrated, such as mailboxes, public folders, and shared mailboxes.
Timeline: Set realistic timelines for the migration, factoring in the complexity and size of your environment.
2. Pre-migration Tasks
Active Directory Synchronization: Configure directory synchronization between your on-premises Active Directory and Azure Active Directory. This ensures that user accounts and attributes are synced to the cloud.
Hybrid Deployment: Deploy a hybrid configuration to facilitate coexistence between on-premises and cloud environments during the migration.
Mail Flow Configuration: Adjust mail flow settings to route mail through Exchange Online once the migration starts.
Test Mailboxes: Create test mailboxes in Exchange Online to validate the migration process and troubleshoot potential issues.
Execution Phase
3. Migration Execution
Cutover vs. Staged Migration:
- Cutover Migration: Suitable for small organizations with fewer than 150 mailboxes. All mailboxes are moved simultaneously.
- Staged Migration: Ideal for larger organizations with more than 150 mailboxes. Mailboxes are migrated in batches over time.
Batch Migration: Divide mailboxes into manageable batches and schedule the migration accordingly.
Public Folder Migration: Carefully plan and execute the migration of public folders, ensuring accessibility and continuity.
Monitoring and Troubleshooting: Constantly monitor the migration process, identify and resolve issues promptly.
4. Post-Migration Tasks
Decommission On-Premises Exchange: After verifying that all mailboxes and data have been successfully migrated, decommission the on-premises Exchange Server.
Final Cutover: Complete the cutover by redirecting mail flow to Exchange Online and configuring Autodiscover and DNS records.
End-user Training: Educate users on the new features and functionalities of Outlook and other Microsoft 365 applications.
Post-Migration Support: Provide ongoing support and assistance to users, resolving any issues that arise.
Best Practices
5. Best Practices for a Successful Migration
Detailed Documentation: Maintain comprehensive documentation throughout the migration process, recording each step and configuration change.
Communication: Keep stakeholders informed of the migration status, addressing any concerns and answering questions promptly.
Testing: Rigorous testing is crucial for validating the migration and ensuring that all systems are functioning as expected.
Rollback Plans: Have a rollback plan ready in case unexpected issues arise during the migration.
User Engagement: Involve end-users in the migration process to ensure smooth adoption and minimal disruption.
