| As part of our commitment to security and performance in our webhosting environment, we are upgrading MySQL on your server from version 5.0 to version 5.1. This is an important change to ensure continued compatibility with current and future software, and ensuring the stability and security of services for all customers.
For most customers this change will have minimal impact on your sites hosted with us. Most popular software such as Joomla or Wordpress will be fully compatible and will not require any changes, however this may be a good time to check that your installation is up-to-date. Some bespoke software could experience problems if it has been designed around earlier versions of MySQL and we ask all clients to ensure custom code is compatible with the newer version of MySQL. If unsure about this please speak to your web developer. As part of this change we will be recompiling Apache/PHP to the latest release keeping on the same major version, for example Apache 2.2.x and PHP 5.3.x.
The upgrade to 5.1 is not reversible, and version 5.0 is no longer supported by the maker.
For more detailed info about this upgrade please visit the official MySQL page here: http://dev.mysql.com/doc/refman/5.1/en/upgrading-from-previous-series.html
The upgrade is scheduled to start between the 30th of July 2013, and the 31th of July 2013. The upgrades will be started after 9PM BST and shouldn't take longer than 60 minutes per server. We will send further messages on the day that an upgrade will be performed on a server that affects you.
