how to transfer configuration from server to ispconfig3

[tstav]

Hi,
I used to have ispconfig2 installed, but when I tried to upgrade to the latest version, the upgrade failed, deleting the original ispconfig2 folders for some reason.
So I decided to try out ispconfig3 instead (amazing sw so far)
My problem though is that there are already configuration changes made to the system from ispconfig2 that I want to manually transfer to ispconfig3. I there an easy way of doing so, or a specific series of steps that should be taken?
At the moment my ispconfig3 cpanel is completely empty (I have no configured users/emails/databases/sites/dns.
Specifically I want to load my bind dns entries, mysql users and databases, vsftpd users(can it be used instead of pureftp by the way?)apache2 sites and shell users into ispconfig3.

Any help will be appreciated.

There is no migration utility available as ispconfig 2 and 3 use a completely different setup and have different system requirements. You will have to recreate the email domains, websites, users etc. manually.

Regarding your update problem with ispconfig 2, please see the ISPConfig 2 release notes. There are a few additional packages neded for spamassassin for the latst releases. The /root/ispconfig folder is always deleted during update, you simply have to run "mkdir /root/ispconfig" and then run the setup script again to redo the update, ispconfig will rebuild the /root/ispconfig folder then automatically. So your ispconfig 2 system is not broken, ispconfig 2 is just not fully updated yet.
