Thanks for the reply! This is their response regarding Debian 9: I already have working ESXi 6.5 and can install VMs so I will delete Debian 9 and create Debian 8 VM. Quick question, VM that is available from https://www.howtoforge.com/list-of-downloadable-vmware-images is Debian 8 is it ok to do apt-get dist-upgrade so that it upgrades to Debian 8.8? will it mess up ie. PHP 5.3?
