What you need:
Both servers must support the IMAP email protocol. All myhost hosting packages can connect using IMAP.
The password for the email account you are trying to migrate.
An IMAP-capable local email client. Common email clients like Outlook, Apple Mail, and Thunderbird support IMAP mail accounts.
Procedure:
1. Create the same email account on your new server that you had on your old server. Use the same spelling and capitalization.
2. Set the new email account the same password that you used on your old server. You can change the password after the migration process is done, if required.
3. In your local email client, create two new email accounts.
- These will both be for the same email address.
- They will both use the same password.
- They must both be configured to connect using IMAP.
- The incoming server (or IMAP server) will be different for each account. You should use the ip address for the old account and the mail.yourdomain.com for the new account, depending on the dns config. This will avoid any possible DNS conflicts.
4. With both accounts online, open up the inbox for the account that connects to your old server. Drag and drop messages from this inbox to the inbox on your new server.
5. That's it! If you have a lot of emails, give the accounts a few minutes to finish syncing up. Once they're done, your old emails will be in your mailbox on the new server.
