Use 2 ip's for the nameservers.
Buy the pro version it is affordable worldwide.
Backup any configuration files before you edit them.
Check mod security and firewall settings if you get blank web pages or website errors.
For compatibility, i chose the last available PHP version of 7.1 which is PHP Version 7.1.30
