I want move/migration from i-mscp to ISPConfig, its a Live Productive Server with 20 Customers, 40 Domains and 100 E-Mail adress. So i can turn the Server offline for maximal 8 hour (Sunday 00:00 --> Monday 08:00). Any help/tutorial/advise and so on, is appreciated.
I'm very interested in this, too. As far as I can see we will have to migrate manually in all aspects, right? I'm afraid especially concerning mail server reachability during migration and afterwards.... Hope everything will go fine.
