How to go about migrating from ISPConfig 2 to 3
I'm thinking more and more about creating a new virtual machine for ISPConfig 3. Right now I'm running ESXi on my server and have ISPconfig 2 installed on it with around 10-15 domains and 20-30 email accounts.
How should I go about migrating from ISPconfig 2 to 3, while maintaining all of the user accounts, passwords and emails and domains?
I don't really mind manually re-entering things like domains and DNS info, but the thing that I definitely cannot lose from the old server is the email addresses, emails and their passwords (simply because I cannot manually re-create them).
