Upgrade MOSHES from Squeeze to Wheezy

The support team is planning the upgrade of our servers from Debian 6 (squeezy) to Debian 7 (wheezy), which has important implications for member web sites. All members will need to ensure that your web software will be compatible with PHP 5.4. Failure to ensure compatibility may result in your web site failing to work properly.

This wiki page documents the information members need to know, including the schedule for upgrading our MOSH servers from squeeze to wheezy and the communications we plan to have with members regarding this transition. You may also be interested in our technical notes of the upgrade process. We also have a communications page with our drafted email notifications.

What do I need to do to prepare for the upgrade?

The most significant change during this upgrade is the change from PHP version 5.3 to PHP 5.4. PHP is a programming language used by many programs that run web sites, such as Drupal, Joomla and WordPress. Older versions of these programs may not work properly under the newer version of PHP. If you are running Drupal, WordPress, Joomla or any web application that is running under PHP and you are not sure if you are running a compatible version, please check-in with your technical advisors or post a ticket on our support system to ask us to investigate and offer advice.

We expect Drupal sites running Drupal 5 or earlier and Joomla sites running 1.5 or earlier to break after this upgrade. Please take this time to upgrade your sites to a more recent version prior to the upgrade.

If you are running Drupal 6, you must ensure that all your third party modules are upgraded to the most recent versions. In addition, the following third party modules are known to have problems with PHP 5.4:

  • panels: If you are running panels you must upgrade to the dev version (6.x-3.x-dev, 2013-10-01). 6.x-3.10 will break.
  • draggableviews: If you are running draggableviews, you must upgrade to the dev version (6.x-3.5+5-dev, 2013-Sep-30). Version 6.x-3.5 will break.

If you are running CiviCRM, please upgrade to 4.1 (ideally, which should take care of all problems) or 4.3.8 which needs a small patch (documented in comment:9:ticket:8049) if you are using the CiviCRM views module. You may be able to succesfully run earlier versions of CiviCRM, but you will need to add error_reporting(0); to your civicrm.settings.php file to avoid PHP strict warnings.

Why are we making this change?

The security of our shared servers depends on running software that is being actively maintained and patched when security flaws are discovered. If just one site is insecure, then all members on that server become vulnerable. We regularly experience problems (slow downs on servers, blocked email) that are caused by members running old versions of web software. We fully recognize that upgrading web applications is time consuming and expensive. However, we also know that this process is a necessary one in order to preserve both the security of your site as well as the over-all security of our organization.

Communications and Upgrade Calendar

Week of Saturday November 2, 2013
