Migration from Rackspace using IMAP

If your organization is currently using Rackspace Email and is planning to move to Zoho Mail, you can migrate existing emails using the IMAP migration option available in the Zoho Mail Admin Console.

Before initiating the migration, it is crucial to ensure that each user’s data from the Rackspace server has a corresponding account in Zoho Mail to which the data will be transferred. Refer to our help page for detailed instructions on adding users in Zoho Mail.

The steps involved to migrate the emails from Rackspace Email to Zoho Mail are:

1. Add Server Details for IMAP Migration
2. Add Server Settings for IMAP Migration
3. Create Migration
4. Add users for migration
5. Start Migration

Adding the IMAP Migration

Add Server Details for IMAP Migration

To begin migrating emails from Rackspace Email to Zoho Mail, the following server configuration details must be provided.

• Server Port: Zoho Mail supports ports 993 (SSL) and 143 (Non-SSL) for IMAP.
• SSL Type: Only trusted certificates are supported. Self-signed SSL certificates are not allowed for security reasons.
• Maximum Connection Limit: This is the maximum number of connections the server accepts at a time. For example, if the limit is set to 5, the migration process will start simultaneously for five users, making it faster.
• Path Prefix: Some IMAP servers require the path prefix details for connecting and retrieving emails.

Follow the below instructions to add server details for IMAP migration:

1. Log in to Zoho Mail Admin Console and select Data Migration from the left pane.
2. Click Start data migration for the first migration, or click  + Create for subsequent migrations.
   
3. Enter a Name for the migration.
4. Choose Add new server details in the Select saved server details drop-down,
5. Select IMAP in the Select Protocol/Application drop-down menu.

7. Select SSL Port Number 993 under security.
8. Enter the Path Prefix, if your source server mandates it.
   
9. If you want to proceed without the SSL certificate check, select Skip certificate check, and click Add.

The server details you added will be saved on the Saved Server Details page, and you can use them for performing other migrations just by picking them from the drop-down.
