While our newer DrupalCONCEPT clusters already run PHP 5.3, mainly the ones we built in 2010 still have PHP 5.2 installed. The PHP project stopped its support for PHP 5.2 in August 2011 and we’ve decided, for obvious maintenance and security reasons, to upgrade all our clusters to PHP 5.3 .

Affected by this upgrade are all DrupalCONCEPT clusters from pro07 to pro25 and elite4 to elite6 .

We’ll upgrade those clusters from PHP version 5.2.10 to 5.3.2 (using the original Ubuntu 10.04 LTS packages).

All upgrades will take place over night from Saturday, 2012–03–03 23:00 CET , to Sunday, 2012–03–04 05:00 CET.

To prevent problems and outages, we urge all customers that are using the clusters mentioned above to test their websites with PHP 5.3 and to install necessary Drupal and module upgrades in good time before the upgrade deadline. We recommend to run those tests in a local test environment, better yet on a staging website instance on the DrupalCONCEPT hosting platform.

If you have any questions regarding this upgrade, please let us know! We’ll be more than happy to help you make the change.
