Joomla! Documentation™

Bevor Du beginnst, ist es notwendig zu wissen welche Joomla! Version Du benutzt. Das gilt ganz besonders bei der Änderung einer Major-Version. Wenn Du nicht weist, was eine Major-Version ist, solltest Du mehr über den release and support cycle der Joomla! CMS Versionen lesen. Joomla! wird mit den folgenden Versions-Bezeichnungen, [Major].[Minor].[Wartung]. Zum Beispiel, Version 3.4.4 ist Joomla! Major-Version 3, Minor-Version 4 und Wartungs-Release 4.

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 and are backwards compatible, eg version 2.5.13 to version 2.5.14 or the version 1.7.x to 2.5.28. For Joomla CMS 3, these updates span all minor and maintenance releases. Some examples are version 3.1.2 to 3.3.6 and 3.3.1 to 3.3.6. Please see the specific pages to review version from and to.
