CWP migration from one VPS to an other.

Hello.
I have a OVZ VPS and I want to migrate my CWP panel with all of the data to the KVM VPS. What is the best and fastest method to do so. I actually do now want to install everything from zero and move all of my backups. Is that the way to move everything faster?.. I actually need to copy everything from one VPS to the other.
Thank you.

unfortunately re installing and restoring backups is the only method iv found to work first time every time , the problem with a "clone" like transfer is that the config will still need to be changed on the new server because there is server specific config that can't just be copied across, unfortunately there isn't a one click backup / restore feature

Oh I see. Probably someone knows what kind of configuration files I have to change?..
Or better to reinstall everything?..

its better to be clean

Thank you.
