What is the best way to install CentOS 6? Is there an upgrade facility from CentOS-5.6? If so, how does this compare with a clean installation? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

It appears that version 6 is not an exception[1]. [1] - http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/ch-upgrade-x86.html -- William Hooper

Make a backup of your configuration files. Presumably, your /home and/or /var/www directories are on their own file systems -- this makes things easier, althogh for a production server environment, you really want to do a fresh install on a fresh 'machine' (or virtual host), and then migrate services and content, testing as you go.>-- Robert Heller -- 978-544-6933 / heller at deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments
