what the best way for re-install cwp with low risk

Is your server meet the minimum hardware requirements mentioned here:- http://centos-webpanel.com/system-requirements

for first installation its ok and work fine
but for re-install ...

my server ram and cpu ... = 6GB Ram& cpu 8core

is any way to solve this?

how to  have a clean/fresh installation of  centos7
please tutorial for commands or link for that

thanks

you need to format your server and do a clean installation if this installation failed, if it fails again on the clean install I recommend to contact cwp support.
