Migration from Google Workspace

Migration from Google Workspace to Zoho Mail

Migration from Google Workspace (Google Apps)/ Gmail accounts:

Zoho Mail provides flexible options to migrate from Google Workspace accounts. Mail, Contacts and Calendar data can be migrated from the respective Google Workspace accounts to Zoho Mail. The respective user accounts need to be created in Zoho Mail before adding the migration. Follow this link for detailed instructions on user addition.

Google Workspace(Gmail) behaviour during migration

In Google Workspace(Google Apps/ Gmail) accounts, the emails are organised using labels. The labels are treated as folders and the email are migrated to the respective folders. Since more than one label can be applied to an email, the email appears in more than one folder. 

During migration to Zoho Mail, there will be duplication of email under different folders, based on the labels applied to that email in Gmail. This also causes the size of the mail account to bloat up, due to the duplication of email. 

Ex: If an email in Gmail has 3 labels, the email will be migrated 4 times, if you do not choose the relevant settings. If the email of size 10 MB has 3 labels, Inbox, Work and Important, the email gets migrated under Inbox, Work and Important folders in Zoho Mail and ends up occupying 30 MB of space.  

To avoid this situation, try to keep the overlapping labels in your Gmail account to a minimum.

All the emails present under the 'Important' label will also be available under the 'Inbox' label in your Gmail account. If you want to save some storage in your Zoho Mail account, you can choose to add the 'Important' label to the exclude folder list while adding the settings for migration.

Adding the Google Workspace Migration:

Adding server details for migration from Google Workspace:

  6. If you choose the All Folders option, you can choose to skip any folders during migration using the Exclude Folder List option.
  7. 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. Enter the names of the folders within double quotes ("Folder1"), in which case only that folder will be excluded. If you want all subfolders under a parent folder to be migrated enter the folder name followed by /* within double quotes ("Folder1/*"). For detailed information on the convention, refer here.

  9. In the Include Folder List, enter the names of the folders within double quotes ("Folder1"), in which case only that folder will be included. If you want all subfolders under a parent folder to be migrated enter the folder name followed by /* within double quotes ("Folder1/*"). For detailed information on the convention, refer here.
  10. Under Emails to migrate, select whether you want to migrate all the emails or the emails that you have received after a specific date.
  11. 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.
  12. There are multiple other customizations you can choose to apply to your migration from the Other preferences section: 
    • Exclude Inbox Mails in case it has more than one label - An email may have multiple labels in your Gmail Inbox, such as 'ToDo' or 'Work'. If you select this check box, those emails will not be migrated to your Zoho Mail Inbox. But they will still be migrated under other labels as folders in Zoho Mail.
    • Mark Important as Tag - Emails that have been marked as important in your Gmail account can be added under the ZMImportant tag in Zoho Mail while migration.
    • Mark Starred as Tag -  All the starred emails in your Gmail account can be added under the ZMStarred tag in Zoho Mail using this option.
  13. Finally, click ​Add.

 The settings you added will be saved in the Saved Settings page, and you can use it for performing other migrations just by picking it from the dropdown.

Prerequisites for Calendar Migration from Google Workspace:

  • To ensure complete migration, all the users present in the respective Google Workspace account need to be created in Zoho Mail before calendar migration.
  • For the Calendar data to be migrated correctly, the domain name in Zoho Mail has to be the same as the domain name in Google Workspace. For example, if your domain in Google Workspace is abc.com, your domain name in Zoho Mail should be the same.

Convention for mentioning folders:

  • In case you want to mention a specific parent folder (E.g. Reports), enter it as "Reports".
  • In case there are multiple subfolders under Reports and you want to mention all the subfolders, enter it as "Reports/*"
  • In case there exists a subfolder under Reports named 2016, and you want to mention this particular subfolder, enter it like this - "Reports/2016". 
  • If you want all the subfolders under Inbox, only the Marketing folder without the subfolders, and a specific subfolder, 2012, alone under the Sales Reports folder to be mentioned, you will have to type the Folder List like this - "Inbox/*", "Marketing", "Sales Reports/ 2012".

Creating a new migration:

  1. In the next step, Enter the Maximum Connection Limit. This refers to the maximum number of 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.

Adding user details for migration from Google Workspace:

Zoho Mail provides three options to add user accounts for migration. They include

Manual User Addition:

  2. Click Add to add the account details manually.​
  3. Provide the Google Workspace email address of the user and the respective Zoho account email address​ for this user.
  4. Choose whether you want to prioritize the migration of this user over other users, and click Add.

This will add the users for the migration.

Steps to Import users from CSV file:

Instead of manually adding the users for migration, you can also add the user details to 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.

  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 screen.

Note:

  • The source account and the destination account details should mandatorily be entered in the CSV file.

Fetching User Accounts from source server:

You can populate the account details in Zoho Mail directly from the source server.

  1. From the Migration list, select the migration to which you want to add the source and destination user account details. 
  2. Click Add to add the account details 
  3. Click Fetch to directly populate user details.
  4. Select the users whose accounts need to be migrated.
  5. Finally, click Add.
  6. A preview of all the users selected, along with details about whether they were added or not will be shown on screen.

Starting the migration process

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 migration that you want to start from this page, 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.
  6. Similarly, you can also view the statistics for Contacts migration by going to the Contacts tab.
