I just made the switch to OS X Server over the weekend for email. I provide email for family members with a family domain. I initially was using Google Apps for a couple years and then had to look into alternatives when they dropped active sync support. I moved everything over to Windows Live Domains last November and was pretty happy with the new setup, but now MS is discontinuing that service. MS wants everyone to migrate to Office 365 accounts which Id consider if it was a flat yearly fee, but they charge per user and I cant justify $500 a year for a few family users and I only need email not access to Office apps as well.
I know this isnt the ideal way, but I am using my home connection for this with a static IP from http://www.mystaticip.com. Im still on the trial, but it seems to be working well. Im also using this as a backup MX in the event that the server or home connection goes down at any time. http://www.junkemailfilter.com/spam/free_mx_backup_service.html
As far as migrating data, I did what was mentioned above by setting up both accounts in Mail.app and then dragging and dropping the email over to the new account. I just let my users know when it was going to happen, reset their live passwords and then provided them with the new login details once everything was in place. I also setup roundcube for web access.
