Technical Advantages of Migrating Gmail to IMAP

Users often migrate emails from Gmail to IMAP for better security and improved compatibility. Look at a few advantages of this migration:

  • IMAP enables users to check their emails anywhere and on any device. It ensures that emails stay synchronized.
  • By creating an IMAP backup, users build a safety net or a secondary copy of their email communications.
  • Users can keep their emails organized via IMAP irrespective of which platform they are working on. IMAP preserves the personalized folder structure.
  • The IMAP protocol allows users to choose the preferred email service without any loss of email messages.
  • In IMAP-enabled email clients, users can read, search, and compose emails without internet connectivity. 

Multiple Ways to Migrate Gmail to IMAP Account

The email migration from Gmail to an IMAP account can be done in two ways. First, using a manual way with the help of an email client or forwarding. Second, via a professional backup tool for error-free results. 

Way 01: Move Gmail Emails to IMAP via Email Client

One can use any email client, such as Thunderbird, Apple Mail, or Outlook, for this migration. It is a simple and easy way to transfer the email data between accounts.

Step-by-step process to be followed:

Step 01: Enable IMAP in Gmail Account

  1. First, log in to your Gmail email account
  2. Then, click on Settings > See all Settings > Forwarding and POP/IMAP.
  3. In the IMAP Access tab, choose Enable IMAP and save the changes.

Step 02: Add Gmail and IMAP Accounts in Thunderbird

  1. Launch Mozilla Thunderbird, then click Menu.
  2. Choose Account Settings > Account Actions > Add Mail Account.
  3. Next, type in your Gmail account credentials and choose IMAP.
  4. Thunderbird will auto-detect the server settings and wait for emails to get synced.
  5. Similarly, add the other IMAP-enabled email account.

Step 03: Transfer Gmail emails to IMAP

  1. Now, select a Gmail folder you need to migrate to an IMAP account.
  2. Select the emails and drag and drop them to the IMAP account folder.
  3. Wait for the emails to get synced.

Drawbacks: Since Thunderbird uploads each email one by one, it takes time to sync large mailboxes. If the internet connection is slow, there is a high chance of sync errors. This process may not retain the folder structure of some of the Gmail labels.

Way 02: Migrate Emails from Gmail to IMAP by Forwarding

In this method, users can only move a small number of Gmail emails to an IMAP account. They can selectively migrate emails to IMAP one by one.

The following are the instructions to begin the process:

  1. Sign in to your Gmail account with your Email ID and Password.
  2. After that, navigate to the folder containing the desired emails to be migrated.
  3. Click on the email one by one and go to the Forward button.
  4. Now, input the destination IMAP email address and tap Send.
  5. You can now manually organize the emails in the IMAP account folder.

Drawbacks: Opening each email one by one will be a time-consuming process. After forwarding the emails, the original metadata may change. The email formatting may get changed, especially, inline images or HTML elements.
