In the Desktop world upgrading to the new and latest version of a Linux distribution is almost mandatory, but in the server world, upgrading is more complicated. The first step in updating a server is to check what software versions come with the new distribution version and then check whether the running custom (application) software supports the software versions. For example, updating to a new distribution version, which comes with PHP 8.1, but the current application supports only 7.4 is not very wise and in addition, the current version may have years of support in the future.
