Anyone installed Cloudmin on OVH recently

It’s OVH.
Kimsufi doesn’t resale VPS anymore.
In fact they are kicking me out of an end of line product with no option to clone it. It was a readymade release CentOS 6 with a very light and very easy to use module within webmin known as OVHM

SO I subscribed to a new VPS for testing. I have a huge system to transfer, a dozen websites… Such a secured server, I worked years and years to fine tune it :-). So now I’m on panic. Tried Virtualmin, VestaCP, CentOS web panel, ISPconfig (more than 8 hours of work) and back to virtualmin as i’m used to use webmin on CentOS. Fact is, the main website is a huge php homemade site with more than 20 years of work on it. tens of thousand of lines of coding. nearly a thousand files including hard coded /home/[user]/www
Of course, I could do a script to scan and replace with …/…/something
I need multiple php versions installed to slowly upgrade it.

Issue is VestaCP running php7 without a way to downgrade it, CWP stopped working completly when I changed the PHP version within the panel to see if it worked !
so back to virtualmin wich I’d like to use. Trying actualy a solution suggested in my other post (https://forum.virtualmin.com/t/clean-new-centos-install-no-php-working/104432/5)
