63 63  When upgrading make sure you compare your ##xwiki.cfg##, ##xwiki.properties## and ##web.xml## files with the newest version since some configuration parameters may have been modified or added. Note that you should add ##xwiki.store.migration=1## so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.

66 +We made important changes to the [[Solr schema>>http://design.xwiki.org/xwiki/bin/view/Design/SolrSchema]] in this release and unfortunately we don't have support for automatic Solr search index migration at this point. If you upgrade from XWiki 4.3 Milestone 2 or greater then **you have to delete the 'solr' folder** from the configured permanent directory of your XWiki instance. The Solr index will be recreated automatically and the entire wiki/farm will be re-indexed after a server restart.
