[xwiki-users] Fwd: upgrade from 5.1

Hi, I'm trying to upgrade our 5.1 xwiki to 5.3 and I get a lot of warning messages (5.1 to 5.2.2 upgrade has the same result): WARN o.x.v.i.DefaultVelocityEngine - Deprecated usage of getter [com.xpn.xwiki.api.DeprecatedContext.getMacro] in xwiki:XWiki.XWikiUserSheet@78,32 WARN o.x.v.i.DefaultVelocityEngine - Deprecated usage of getter [com.xpn.xwiki.a pi.DeprecatedContext.getDatabase] in xwiki:XWiki.XWikiUserSheet@81,22 etc.. I tried different solutions (I'm using standalone version): - replace war - copy database and conf file on a fresh install - export/import What could I do to remove all these messages? What is the less painfull way to migrate a wiki (I read the doc http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Upgrade). I really think that there's should be a simpler way to upgrade xwiki for standalone version. Each of the above solution has its drawbacks. Thanks
