Migrating and upgrading mailserver

I have new and powerful server for mail server. So now I am in the process of migrating my mail data and settings to the new server. But it is not as simple as copying a directory. It involves many things. Luckily some of them, you can just copy to the new server.

I am most concerned with the mail messages as they contain important messages for day-to-day operations and conversations. I will tell you more after the migration is complete.

cheers,
