+			Fedora 22 introduces the Preupgrade Assistant, a diagnostics utility which assesses the system for possible in-place upgrade limitations and provides a report with the analysis results. It is based on a module  system, with each module performing a separate test, checking for package removals, incompatible obsoletes, changes in libraries, names changes, or deficiencies in the compatibilities of some configuration files. The Preupgrade Assistant does not modify your system except for storing log files.

+		<para>
+			Data gathered by the Preupgrade Assistant can be used for migrating the system using a Kickstart file. It also provides post-upgrade scripts to finish more complex problems after an in-place upgrade. The preupgrade-assistant-contents package is part of the preupgrade-assistant package and it delivers the set of scripts and plug-ins that are used to assess the system. Every module runs its own test and display   an exit code that represents the result of that text (for example <literal>PASS</literal>, <literal>FAIL</literal>, <literal>NEEDS_ACTION</literal>, etc.). Contents can be done by users on the base of the Packaging Guidelines here: <ulink url="http://fedoraproject.org/wiki/Packaging:PreupgradeAssistant"/>. Package owners are responsible for adding a module if it is suitable, for example changes in the MariaDB database between system versions.
