Joomla! Documentation™

Avant de commencer, il est essentiel que vous sachiez quelle est la version de Joomla! que vous utilisez. C'est d'autant plus vrai si vous passez d'une version majeure à une autre. Si vous êtes déjà en pleine confusion ou si vous ne savez pas ce qu'est une version majeure, vous devriez en apprendre davantage en lisant les cycles de support et des mises à jour des versions du CMS Joomla. Les désignations de version de Joomla! sont les suivantes, [majeure].[mineure].[maintenance]. Par exemple, la version 3.1.5 est la version majeure 3 de Joomla, 1 mineure et 5 la version de maintenance.

Since version 1.7, the updating and upgrading of Joomla are built into the administration interface as a component. The terms updating and upgrading might be used interchangeably. In many ways, updating and upgrading are alike since Joomla 1.7, but you will need to pay very close attention to the details. To help define them better, it is recommended you use the term migration which would be defined as a major.minor(2.5) to a different major.minor(3.1) version.

Simple Updating

Updates are an easy update to the next maintenance release, for example version 2.5.13 to version 2.5.14. This would be a maintenance release of the 2.5 version.
