Upgrade RT 3.6.7 to 3.8.8 - Debian 5.0(lenny) to 6.0(squeeze)

Procedure that worked for me(upgrade from RT 3.6.7 with MySQL on debian Lenny 5.0, to RT 3.8.8 on Debian Squeeze 6.0 with MySQL):

First backup.

Upgrade lenny to squeeze as usual.

Then

apt-get install request-tracker3.8 rt3.8-db-mysql

Use the same name for instance, and choose no for dbconfig.

Copy needed configuration snippets from /etc/request-tracker3.6/RT_SiteConfig.d/ to /etc/request-tracker3.8/RT_SiteConfig.d/ directory.

Remove old RT with:

apt-get --purge remove request-tracker3.6 rt3.6-clients rt3.6-db-sqlite rt3.6-apache2

Run

update-rt-siteconfig to refresh RT_SiteConfig.pm.

Then we should upgrade database with:

/usr/sbin/rt-setup-database-3.8 --action upgrade --dba rtuser --dba-password

Important: choose versions from 3.6.7 to 3.7.87.

Afterwards do

perl /usr/share/request-tracker3.8/etc/upgrade/upgrade-mysql-schema.pl rtdb rtuser 'yourRTuserpassword' > queries.sql

mysql -u rtuser -p rtdb < queries.sql

Then again run:

/usr/sbin/rt-setup-database-3.8 --action upgrade --dba rtuser --dba-password

this time choose version from 3.8.0 till the end.

Then configure apache, something like

Include /etc/request-tracker3.8/apache2-modperl2.conf
RedirectMatch ^/$ /rt
in /etc/apache2/sites-available/default.

Restart apache.

Voila! That should be it!
