Installing CloudLinux on existing Plesk 12 server

[GlennT]

Hi

I would like to install CloudLinux on an existing Plesk 12, Centos 6-64 server with about 100 domains.

I also have 2 versions of php: 5.3.x. and 5.4.x

Can I install CloudLinux on a server with existing domains without breaking the server or websites?

I would like to hear from others of their experience installing CloudLinux on an existing hosting server and if it created lots of problem or broke websites or if the experience was relatively smooth.

Any insight anyone can provide would be greatly appreciated.

thanks
G
