Due to a massive hacker attack on our mailserver we have to upgrade the system. I have no experiances with Debian/Linux and therefore I am asking for your help.

Hi Roland,

Migrating to the VM is somthing that can be achieved with the KMSrecover tool. You can backup Kerio on your current system and use that to restore onto the VM.


If you do go down the KMSRecover route I would suggest creating a 2nd virtual drive for your mail store to be restored to. The article below shows you how to do this with the Virtual Appliance.


I would highly recommend reading through this article to see what you can do with the appliance:


I hope some of this information helps,

Personally I think it's not a good idea install Kerio Connect at OS with which you are not familiar, especially if you need secure it against attackers.

For 32bit Kerio Connect:
apt-get install sysstat
wget http://cdn.kerio.com/dwn/connect/connect-8.4.2-4065/kerio-co nnect-8.4.2-4065-linux-i386.deb
dpkg -i kerio-connect-8.4.2-4065-linux-i386.deb

(I hope I did not forget for some dependency added in 8.x)
