Migration from Titan Mail to Zoho Mail

If your organization's email was previously hosted with Titan Mail, you can migrate your emails via IMAP from the Zoho Mail Admin Console. An admin must first create the user accounts in Zoho Mail before migration. Refer to the Add Users help page for more details. Once the user accounts are created, emails from the source server can be migrated to the respective user accounts in Zoho Mail.

IMAP Migration from Titan Mail to Zoho Mail

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

• Adding server details
• Adding server settings
• Creating the migration
• Adding users for migration

Add Server Details for IMAP Migration

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 server configuration.
4. In the Select saved server details drop-down, choose Add new server details.
5. In the Select Protocol/Application drop-down menu, choose IMAP.
   
6. Select Others in the source server type and enter imap.titan.email in the Source server address.
7. Select SSL Port Number 993 under security.
8. 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 it for performing other migrations just by picking it from the drop-down.

Add Server Settings for IMAP Migration

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

1. Enter a name for the server settings.
2. Under Folders to migrate, you can choose either the All folders or Specific folders option. 
3. If you choose the All folders option, you can choose to skip any folders during migration using the Exclude Folder List option.
4. The skip folders option will be handy when the admin reruns migrations for the same set of users for some new emails or missed emails. For more details, refer to folder conventions.
5. If you choose the Specific folders option, you can specify the folders that need to be included in the Include Folder List. To add a folder in the Include Folder List, refer to folder conventions.
6. Under Emails to migrate, select whether you want to migrate all the emails or the emails that you have received after a specific date.
7. In Enable POP access for the migrated emails, select Yes if you want your users to view the migrated emails when the account is configured as POP in other email clients. Otherwise, select No.
8. Click Add and proceed to Create migration.
   

​The settings you added will be saved on the Saved Settings page, and you can use it for performing other migrations just by picking it from the drop-down.

You have successfully configured the server settings for an IMAP migration. Proceed to Create migration procedure.

Create Migration

To complete creating a migration, follow these steps:

1. Enter a Maximum Connection Limit.
   The maximum connection limit is the number of maximum connections accepted by the server at a given time. For example, if you provide 5 as the maximum connection limit when the migration is started, the migration process will be started simultaneously for 5 users. The migration process will be faster when there are parallel migrations happening between the servers.
2. Select whether you would like to Pause the migration when the storage reaches 80% or 95%, and finally click ​Create.
   

​You have now successfully created a migration. Proceed further to add users and start the migration.

Add Users for Migration

Zoho Mail provides two options to add user accounts for migration:

• Manual user addition
• All bulk users through CSV

Manual User Addition

To add users manually, follow these instructions:

1. From the Migration list, select the migration for which you want to add users.
2. Navigate to the Users tab and click Add.
   ​
3. Enter the Source user name, Source password and Select the destination email address.
4. Choose the priority for the migration and click Add. The user gets added successfully. Proceed to the Start Migration step.
   ​​​

Import Users for Migration via CSV

Instead of manually adding the users for migration, you can add multiple users in an excel sheet, save it as a CSV file and upload it. The user accounts mentioned in the CSV will be uploaded for migration.

1. From the Migration list, select the migration to which you want to add the source and destination user account details. 
2. Click Import to upload the user accounts using a CSV file.
   
3. The format for entering the User Details in the CSV file can be found in the sample file attached in the pop-up.
4. Once you have prepared your CSV file, click Browse Files, and choose the CSV file that you would like to import.
5. A preview of all the users in the CSV file, along with details about whether they were imported or not will be shown on the screen.

Start Migration

Once you have added the user accounts for the migration, you can start the migration. Ensure that the source passwords are not changed after adding the users for migration. The password should be the same until the entire migration process is completed. 

1. Click the Start Migration button after adding the users. If you have navigated out of the page where you added the users, select the desired migration from the migrations list, and click Start Migration.
2. You can view the progress and statistics regarding the migration on the same page.
3. Detailed statistics regarding each user's migration can be viewed by clicking on their email address on the migration progress page.​
4. For mail migration, detailed reports along with folder information will be available.
5. Click Mail Failures to view the detailed information about the folder-wise migration details.
