I have launched apt-get to update my apache2 installation and to upgrade from php4 to php5, apache2 and php5 were installed but my plesk 9 installation were disappeared!
I already have plesk autoinstaller utility on my Debian system, but launching it Plesk results not installed!!!
How can I repair my Plesk 9 installation without removing existing websites, mailboxes etc.?
All my services seems to work correctly (apache with all virtualhosts, mysql, dns and mail servers are all working)... Does a Plesk autoinstaller execution delete my current vhosts, databases, mail accounts etc? Is there any way to have only plesk panel installed without touching the other service's configuration and operativity at all?
What should I backup in order to prevent data loss?
Thanks you all in advance.
