[xwiki-users] XWiki Enterprise 3.0.36132 -> upgrade to 3.4 ?

Hi. I have XWiki Enterprise 3.0.36132 and would like to upgrade to latest version. I have tried to upgrade directly to 3.4 but as it produced error message I tried to upgrade in steps.. Upgrade to 3.1.1 was ok, no db migration was needed and installed the .xar without problems. Then upgrade to 3.2.1 produced the following: ---------------- Servlet.service() for servlet [action] in context with path [/xwiki] threw exception [com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3201 in 3: Exception while saving document xwiki:XWiki.XWikiUsers Wrapped Exception: Error number 3211 in 3: Exception while updating archive XWiki.XWikiUsers Wrapped Exception: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: could not load an entity: [com.xpn.xwiki.doc.rcs.XWikiRCSNodeContent#component[docId,version1,version2]{docId=495778886, version2=1, version1=2}]] with root cause com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3201 in 3: Exception while saving document xwiki:XWiki.XWikiUsers Wrapped Exception: Error number 3211 in 3: Exception while updating archive XWiki.XWikiUsers Wrapped Exception: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: could not load an entity: [com.xpn.xwiki.doc.rcs.XWikiRCSNodeContent#component[docId,version1,version2]{docId=495778886, version2=1, version1=2}] at com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:422) at com.xpn.xwiki.XWiki.getXWiki(XWiki.java:491) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:136) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:116) ----------------- the hibernate configuration is --------------------- <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="show_sql">false</property> <property name="use_outer_join">true</property> <property name="dbcp.defaultAutoCommit">false</property> <property name="dbcp.maxActive">50</property> <property name="dbcp.maxIdle">5</property> <property name="dbcp.maxWait">30000</property> <property name="dbcp.whenExhaustedAction">1</property> <property name="dbcp.ps.whenExhaustedAction">1</property> <property name="dbcp.ps.maxActive">20</property> <property name="dbcp.ps.maxWait">120000</property> <property name="dbcp.ps.maxIdle">20</property> <property name="jdbc.use_scrollable_resultset">false</property> <property name="connection.useUnicode">true</property> <property name="connection.characterEncoding">UTF-8</property> <property name="connection.url">jdbc:postgresql://10.10.1.134/xwiki</property> <property name="connection.username">xwiki</property> <property name="connection.password"></property> <property name="connection.driver_class">org.postgresql.Driver</property> <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property> <property name="connection.provider_class">com.xpn.xwiki.store.DBCPConnectionProvider</property> <property name="connection.pool_size">2</property> <property name="statement_cache.size">2</property> <mapping resource="xwiki.hbm.xml"/> <mapping resource="feeds.hbm.xml"/> <mapping resource="activitystream.hbm.xml"/> </session-factory> </hibernate-configuration> --------------------- Any help would be appreciated..
