How to Migrate IMAP Email to Gmail Manually?

One can use Gmail’s Fetcher settings, Google Workspace migration services or email software like Thunderbird to migrate an IMAP email account to Gmail.

Pre-requisites:

You’ll need the active login details for your original IMAP email and new Gmail account.
Your Gmail should also have enough space to hold all emails.
You should know the IMAP incoming server address and port number (usually 993) as well as the IMAP settings of your current service provider.
You should have IMAP access enabled in your current email provider’s settings.
If you have enabled the two-step verification for your Gmail account, you have to ensure that you have the Gmail app password ready.
You also need to make sure that you have the requisite permissions for allowing IMAP access for your email provider.
Last but not the least, you’ll need a stable internet connection for smooth transfer.

Method-1: Via Gmail Mail Fetcher (For Personal Gmail)

Open your Gmail Account.
Click on the Gear icon (Settings) at the upper right corner, and choose See All Settings.
Go to the Accounts and Import tab.
Locate Check mail from other accounts and click the button Add a mail account.
Provide your former email and proceed with the requirement of providing IMAP server details as well as port and password.

Method-2: Through Google’s Data Migration Service (for Google Workspace)

Log on to Google Admin Console using Super Administrator account.
Go to the Data section > Import and Export > Data Migration menu.
Press Migrate button on IMAP tile.
Choose IMAP server type, connect it, and verify.
Provide user mapping information via CSV or manually, provide filtering or date range if necessary, and start migrating your data.

Method-3: Manually Moving Emails via Thunderbird Email Client

Get a copy of an email client, say Mozilla Thunderbird.
Make sure to configure both your old IMAP account and your new Gmail account.
Set up whatever folder/label is required for your Gmail account.
Take your pick and drag the required messages from your old IMAP account right into the Gmail folders.

Limitations of Manual Methods

Gmail’s Mail Fetcher only receives incoming emails and is unable to copy previous folders and outgoing emails.
Google’s Data Migration Service is available strictly to Google Workspace admins, excluding the free Gmail users from this opportunity.
The usage of email client software like Thunderbird with respect to migration means that your computer must be ON for the duration of the transfer process.
Generally speaking, manual options are devoid of advanced filtering possibilities, thus requiring one to switch all the emails without any possible selectivity.
Working with mailboxes of a big size might make the manual migration process not successful.

Q: How long does it take for the IMAP migration process into Gmail to be over?

Time period will be based on the size of your mailbox and is typically anywhere from hours to days for the smooth transfer process to be carried out completely.

Q: Do I need any administrative rights to move the IMAP emails to Gmail?
