Devices can deal with tens of accounts while synchronizing data in the background to make the process less tiresome and finally save time and money.

Common Scenarios to Use IMAP Migration Tool

  • Moving from typical web hosting services to specialized services, such as Google Workspace or Microsoft 365, may require changing email hosting providers.
  • Businesses rebranding or shifting domains can be a way of transporting employees’ mailboxes to a new name.
  • Having several email accounts could be a hassle when it comes to private or professional use, but the accounts can be easily merged to create a virtual inbox.
  • Legacy servers or on-premise email systems can be upgraded to the latest digital technology with the stored data not being lost.

How to do IMAP Migration Manually?

Migrating emails manually via IMAP appears to be a complex task but by preparing well, the process will become easy. If you are changing email service providers or moving to a new inbox and want to know how to do the migration process easily, here is a complete guide to migrate emails without losing any important data.

Essential Checklist:

  • You’ll need the active login details for your original IMAP email and the target/destination account.
  • Your target account 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.
  • In case you have enabled two-factor verification in your target account, you have to ensure that you have got app passwords ready and handy with you.
  • 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.

Step-by-Step:

  1. Create a new email account in your favorite desktop email application (e.g., Microsoft Outlook, Thunderbird, or Apple Mail) by following the provided instructions for setting up the new server.
    Add account
  2. Set up your old email account as a second IMAP account on the same email application as your new email.
    Account Settings
  3. Make sure that both email accounts work properly. You need to wait enough time to allow your folders and emails from the old server to download.
    Connect Account
  4. Select the data you want to copy (folders, emails) and send it to your new account mailbox.
  5. Finally, follow the progress of the transfer to make sure that your old account is successfully transferred before deleting it.

Limitations of Manual Methods

  • Due to manual drag-and-drop process, it takes time to download and upload the entire content of the mailbox. This results in working with large mailboxes to be extremely slow.
  • If there are network glitches when transferring data via the drag-and-drop method, there is a possibility of data loss or incomplete synchronization of the folder contents while being dragged.
  • The absence of bulk account automation makes manual transfer highly inefficient.
  • There are no advanced filtering options that could allow utilizing better scheduling of data transfer at times when the network traffic is less heavy.
  • The drag-and-drop method poses a significant likelihood of human errors, like, misplacing the deleted folders.
