Step 1 – Install Imapsync
Imapsync package is available under EPEL package repository. First make sure you have added EPEL on your system or install it first.
$ sudo yum install epel-release
Now, install imapsync package using following command.
$ sudo yum install imapsync
At this stage, your system is ready for migration all data from one email account to other email accounts using IMAP.
Step 2 – Transfer Emails with IMAP
So you are ready for migration. Before migration make sure both accounts have IMAP running and accessible from your system. After that use following command syntax.
$ imapsync --host1
imap.source.example.com\ --user1 [email protected]\ --password1 S0urcePassw0rd\ --ssl1 \ --host2 imap.dest.example.com\ --user2 [email protected]\ --password2 Dest1nat10NPassw0rd\ --ssl2
The command will take a long time as per the size of your source Mailbox. After completing all process, you will see a long list of output. Check the output to find if any error occurred during transfer. Below is the small part of the result.
