164 164  A previous upgrade may have modified the database schema and the data saved in the permanent directory may also have incompatible changes. Thus the best strategy for downgrading is using the [[Alternative Method>>.||anchor="HAlternativeStartfresh2CplusExportandReimportyourdata"]], and that consists of [[exporting your wiki pages as XAR>>xwiki:Documentation.AdminGuide.Backup||anchor="HUsingtheXWikiExportfeature"]] (the ones having your content, not the default wiki pages provided by the XWiki distribution or installed Extensions). Then install the older XWiki version and re-install optional Extensions that you need. Then reimport your XAR in it.

168 +== XWiki won't start and stay stuck on Solr initialization

170 +Solr has a tendency to lock itself when it has several cores to initialize. To workaround that XWiki started created new cores with an option to disable loading the core during Solr init (it's loaded during it's first use) but you might still have existing core without this option set in which case you will have to set it by hand: go to ##<permdir>/store/solr/## and edit each core ##core.properties## file to add {{code language="properties"}}loadOnStartup=false{{/code}}
