Re: QA Tests

If you want to downgrade or test something on an older version or MariaDB on a Debian/Ubuntu server, you can add the old version repository then install the packages of the old version simply ; for example on Debian Squeeze amd64 with 5.5.33 installed and you want to downgrade to 5.5.32 :

echo "deb http://mariadb.cu.be/mariadb-5.5.32/repo/debian squeeze main" > /etc/apt/sources.list.d/mariadb-5.5.32.list
apt-get update

You can find the version string you need with "apt-cache policy mariadb-server-5.5". It's "5.5.32+maria-1squeeze" in my example.

Then install the packages (adjust the version string to your needs) :

apt-get install mariadb-server-5.5=5.5.32+maria-1~squeeze mariadb-server-core-5.5=5.5.32+maria-1~squeeze libmariadbclient18=5.5.32+maria-1~squeeze libmysqlclient18=5.5.32+maria-1~squeeze mariadb-client-5.5=5.5.32+maria-1~squeeze mariadb-client-core-5.5=5.5.32+maria-1~squeeze

It will ask you if you are sure that you want to downgrade.

ps: don't forget to backup your datas if its not a test server, as downgrading could break things and if possible dump all the datas before the downgrade then import it back after.
