Manual Method to Transfer Hosted Exchange to Office 365

Ensure your current Exchange environment is up-to-date and meets the necessary prerequisites for migration. This includes ensuring all servers are patched, and any required configurations are in place. The manual method is very lengthy and complicated. Therefore, for users’ ease, we have divided the process into multiple steps.

Step 1: Verify Domain Ownership

Verify your domain ownership in Office 365. This process involves adding a TXT or MX record to your domain’s DNS settings to prove that you own the domain.

Step 2: Create Office 365 Accounts and Assign Licenses

Create user accounts in Office 365 and assign the appropriate licenses. This can be done manually or via bulk import using a CSV file.

Step 3: Configure Directory Synchronization

If you choose a staged or hybrid migration, set up Azure AD Connect to synchronize your on-premises directory with Office 365. This ensures that user identities are consistent across both environments.

Step 4: Configure Cutover or Staged Migration

Users can migrate the Hosted Exchange to Office 365 by using Cutover migration or staged migration.

For Cutover Migration:

1. Connect Office 365 to Your Hosted Exchange: Use the Exchange admin center in Office 365 to set up a migration endpoint, which connects to your hosted Exchange server.
2. Start the Migration Batch: Create and start a migration batch in Office 365. This process will copy all mailbox data to Office 365.
3. Update DNS Records: After the migration is complete, update your DNS records to point to Office 365 for email delivery.
4. Complete the Migration: Once DNS changes have propagated, complete the migration batch to finalize the process.

For Staged Migration:

1. Create Migration Batches: Divide your mailboxes into batches and create migration batches in the Exchange admin center.
2. Start and Monitor Migration Batches: Start the migration batches and monitor their progress. Address any issues that arise during the migration.
3. Update DNS Records: Similar to cutover migration, update your DNS records to point to Office 365.
4. Complete the Migration: After all batches are migrated, complete the process in the Exchange admin center.

Step 5: Configure Hybrid Migration

1. Install and Configure Hybrid Configuration Wizard (HCW): Use the HCW to set up a hybrid deployment, which creates a seamless coexistence between your on-premises Exchange and Office 365.
2. Migrate Mailboxes: Move mailboxes to Office 365 using the Exchange admin center or Exchange Management Shell.
3. Update DNS Records: Update your DNS records as needed to ensure proper mail flow.

Step 6: Post-Migration Tasks

• Decommission Old Exchange Servers: Once you confirm that all data has been migrated and is functioning correctly, decommission your old Exchange servers.
• Reconfigure Outlook Profiles: Ensure that all users reconfigure their Outlook profiles to connect to Office 365.
• Enable Office 365 Features: Enable and configure additional Office 365 features such as Teams, OneDrive, and SharePoint to fully leverage the platform.
