Step-by-Step: Moving Your Infrastructure from Exchange 2019 to SE

Upgrading from Exchange Server 2019 to Exchange Server Subscription Edition (SE) is a crucial step for organizations aiming to stay current with Microsoft’s evolving Exchange ecosystem. Exchange SE offers continuous updates, improved security, and better integration with modern Microsoft 365 services. Below, I’ll walk you through the process, highlighting preparation, migration options, and best practices.

Exchange 2019 to SE Pre-Migration

Before starting the upgrade, preparation is key.

• System Requirements: Verify hardware and software compatibility with Exchange SE.
• Backups: Always take full backups of databases, mailboxes, and system configurations.
• Active Directory Health: Ensure AD is properly functioning, as Exchange heavily depends on it.
• Permissions: Confirm administrative rights for migration tasks.
• Testing Environment: If possible, simulate the migration in a test lab to identify potential issues.

Manual Migration: Why I Avoid It

Manual migration involves exporting mailboxes to PST files and re-importing them into Exchange SE. While technically possible, it’s inefficient and risky:

• Time-Consuming: Large organizations with thousands of mailboxes face significant delays.
• Data Loss Risks: Manual handling increases chances of corruption or incomplete transfers.
• No Automation: Lacks advanced filtering, scheduling, or incremental migration.
• Limited Scalability: Not practical for enterprises with complex Exchange environments.

For these reasons, manual migration is rarely recommended in professional settings.

Post Migration Guidelines

After migration, follow these best practices:

• Testing: Confirm mail flow, mailbox accessibility, and client connectivity.
• DNS Updates: Adjust DNS records to point to the new Exchange SE environment.
• User Communication: Inform users about the upgrade and any changes in access.
• Monitoring: Use Exchange Admin Center and logs to monitor performance.
• Backup Strategy: Establish regular backups for the new environment.
• Decommission Old Server: Once confident, safely retire Exchange 2019 servers.
