+= Technical notes on upgrading from squeeze to wheezy =
+
+This page details some of the issues we've encountered regarding the squeeze to wheezy upgrades, additional information can be found on #7425, [[squeeeze-wheezy-mosh-upgrade]], and [[support-team/server-upgrade-status]].
+
+== phpmyadmin and php5_cgi ==
+We encountered weirdness with phpmyadmin during the upgrade to rose.
+
+After the upgrade phpmyadmin failed to load with the error:
+
+`navigation.php< not found on the server.`
+
+Apparently the apache module php5_cgi created this problem as
+dis-enabling it fixed the error.  However, we're not sure why the
+module got loaded.  We'll need to pay attention to this issue on
+future upgrades, though that module does not seem to be loaded on
+other moshes.
+
+We also needed to rebuild the phpmyadmin control database.  This was
+done using the info from /etc/phpmyadmi/config-db.php.  It's not clear
+why, but the old phpmyadmin control database did not transfer to the
+upgraded version of the system.  Likely due to choices made during the
+phpmyadmin reconfiguration.
+
+== configuration files to keep ==
+Almost all configuration files will use the package maintainers version.  Here is the short list of things not to modify:
+=== /etc/cron.d/awstats ===
+Keep the currently installed version, we do not actually want awstats to install a cronjob since we manage this cronjob separately.
+=== /var/log/sysstat ===
+The newer version of sysstat asks that you delete the current files, '''Do it!'''.
+=== /etc/default/grub ===
+You will be given the following options for grub:
+
+1. install the package maintainer's version  
+2. keep the local version currently installed  
+3. show the differences between the versions 
+4. show a side-by-side difference between the versions  
+5. show a 3-way difference between available versions
+6. do a 3-way merge between available versions (experimental)
+7. start a new shell to examine the situation
+
+You can safely just choose to keep the local version as there are no meaningful changes to the package maintainers version.
+
+=== rebooting ===
+Upon rebooting rose using `shutdown -h now` the service on rose's host failed to start the kvm process.  This required the following commands from `root@florence.mayfirst.org`:
+
+{{{
+sv down rose
+sv up /etc/sv/kvm/rose
+}}}
