Howto upgrade Bugzilla

Steps in upgrading a bugzilla installation

Become root
Stop mysql: /etc/init.d/mysql stop
Take a backup of mysql: tar zcppf mysql-backup-`date +%x`.tar gz /var/lib/mysql
Install the following packages if they don't exist:
- apt-get -y install libemail-send-perl libgd-graph-perl libnet-ldap-perl libapache2-mod-perl2 libapache-dbi-perl libhtml-scrubber-perl libxml-twig-perl libsoap-lite-perl libchart-perl perlmagick unzip make links libemail-mime-contenttype-perl libemail-mime-encodings-perl libemail-mime-modifier-perl libemail-mime-perl libemail-simple-creator-perl apache2 mysql-server openssh-client
- perl -MCPAN -e 'install PatchReader'
Fetch the wanted bugzilla from http://www.bugzilla.org/download/, in my case 3.0.2
Move the original bugzilla away: mv /home/gtuit/giellatekno/public_html/bugzilla/ to /home/gtuit/giellatekno/public_html/bugzilla.bak/
Unpack bugzilla-3.0.2: tar zxf bugzilla-3.0.2.tar.gz -C /home/gtuit/giellatekno/public_html/
Move the new bugzilla to the correct place: mv /home/gtuit/giellatekno/public_html/bugzilla-3.0.2 /home/gtuit/giellatekno/public_html/bugzilla/
Get settings from the old bugzilla to the new one: cp /home/gtuit/giellatekno/public_html/bugzilla.bak/localconfig /home/gtuit/giellatekno/public_html/bugzilla/.
Start mysql: /etc/init.d/mysql start
Run ./checksetup.pl inside /home/gtuit/public_html/bugzilla

Go to parameters: http://giellatekno.uit.no/bugzilla/editparameters.cgi
