Before you begin, it is essential you know what version of Joomla! you are using. This is especially true if you are changing to a major version. If you are already confused or don't know what a major version is, you should read more about the release and support cycle of Joomla CMS Versions. Joomla is released with the following version designations: [major].[minor].[maintenance]. For example, version 3.9.5 is Joomla major version 3, minor 9, and maintenance release 5.
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.
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.
