[nandulalr]

Imapsync - IMAP synchronization, sync, copy or migration tool. Synchronise mailboxes between two imap servers.

First, you’ll need to install the epel repo (skip if you already have it):

Code: [Select]

# wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
# rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm

Now, use yum to install imapsync.

Code: [Select]

# yum install imapsync

Now that it’s installed, let’s print out the help file and take a look at all of the usefulness of imapsync:

Code: [Select]

# imapsync --help

Now let’s start a sync. Let’s just do one user first.

Create a file email_migration.sh

Code: [Select]

# vim email_migration.sh

Include the below lines into the file, and replace the email ID and password.

Code: [Select]

/usr/bin/imapsync \
   --host1 old.mailserver.com --user1 test@domain.com --password1 mypasswd \
   --host2 new.mailserver.com --user2 test@domain.com --password2 mypasswd

Make it executable:

Code: [Select]

# chmod +x email_migration.sh

Now run it!

Code: [Select]

# ./email_migration.sh

The migration will start now.
