Hello,

Yes, I did that some years ago. Just create a working Dovecot installation and then copy the Maildirs (with correct permissions/owners etc). They probably have some additional housekeeping files from Courier, I believe Dovecot even can use some of them, but anyway they do no harm.

Best wishes Eugene

Hi, All,

I am new here and I need your advises. Here is my story:

I have a mail server like this:

• CentOS 5 32 bit (LAMP)
• Postfix 2.3
• Courier
• MailScanner Courier use maildir to save emails in /home/vmail/<virtual domain>/<user> /

Now I want to build a new system on CentOS 6.4 64bit with postfix, dovecot and migrate all user accounts and their emails.

I already installed CentOS 6.4, postfix and mysql. Also just installed Dovecot v2.2.4 from the RPM. Now I am looking into how to Is there a good instruction on how to do this kind of migration?

I still prefer using the maildir system. If I just copy all users email from old server to new dovecot user maildir, will dovecot see these mails (and sub-folders) ? Do I need do anything extra?

Thanks in advance.

Gao
