[xwiki-users] Migration failed

Hi all, I'm actually working to migrate our wiki from 6.4.5 to 7.2 as it implement the feature we were looking for, since the begining of this year ! So as i did before i upgraded the .war manually, I replaced all config files to match my needs, i'm working on oracle 11g so my hibernate looks like : <property name="connection.url">jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)(ADDRESS=(PROTOCOL=TCP)(HOST=My_server) (PORT=My_Port))(ADDRESS=(PROTOCOL=TCP)(HOST=My_server) (PORT=My_Port))(CONNECT_DATA=(SERVICE_NAME=xwiki)(FAILOVER_MODE=(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))))</property> <property name="connection.username">xwiki</property> <property name="connection.password">xwiki</property> <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property> <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property> <property name="connection.SetBigStringTryClob">true</property> <property name="jdbc.batch_size">0</property> <property name="jdbc.use_streams_for_binary">false</property> <property name="dbcp.ps.maxActive">20</property> <mapping resource="xwiki.oracle.hbm.xml"/> <mapping resource="feeds.oracle.hbm.xml"/> <mapping resource="activitystream.hbm.xml"/> <mapping resource="instance.hbm.xml"/> <mapping resource="mailsender.oracle.hbm.xml"/> i also set the migration parameter in xwiki.cfg xwiki.store.migration=1 But i can't get through it ... my logs looks like : 2015-09-29 13:28:01,157 [coreLoadExecutor-5-thread-1] WARN o.a.s.r.ManagedResource - No stored data found for /rest/managed 2015-09-29 13:28:01,453 [main] INFO o.x.s.s.i.EmbeddedSolrInstance - Started embedded Solr server. 2015-09-29 13:28:01,640 [main] INFO o.x.o.i.s.DefaultOfficeServer - Open Office instance started. 2015-09-29 13:31:19,030 [XWiki initialization] INFO .HibernateDataMigrationManager - Storage schema updates and data migrations are enabled 2015-09-29 13:31:19,420 [XWiki initialization] INFO .HibernateDataMigrationManager - The following data migration(s) will be applied for wiki [xwiki] currently in version [72000]: 2015-09-29 13:31:19,435 [XWiki initialization] INFO .HibernateDataMigrationManager - R72001XWIKI12228 - Make sure xwikidocument and xwikispace tables are in sync 2015-09-29 13:31:19,435 [XWiki initialization] INFO .HibernateDataMigrationManager - Checking Hibernate mapping and updating schema if needed for wiki [xwiki] 2015-09-29 13:31:20,371 [XWiki initialization] INFO .HibernateDataMigrationManager - Starting data migration [R72001XWIKI12228] with version [72001] on database [xwiki] 2015-09-29 13:31:20,387 [XWiki initialization] WARN o.h.u.JDBCExceptionReporter - SQL Error: 904, SQLState: 42000 2015-09-29 13:31:20,387 [XWiki initialization] ERROR o.h.u.JDBCExceptionReporter - ORA-00904: "TRUE" : identificateur non valide 2015-09-29 13:31:20,402 [XWiki initialization] ERROR .HibernateDataMigrationManager - Failed to migrate database [xwiki]... com.xpn.xwiki.store.migration.DataMigrationException: Data migration R72001XWIKI12228 failed [...] Caused by: java.sql.SQLSyntaxErrorException: ORA-00904: "TRUE" : identificateur non valide [...] 2015-09-29 13:31:20,402 [XWiki initialization] ERROR .HibernateDataMigrationManager - Main wiki database migration failed, it is not safe to continue! 2015-09-29 13:31:20,402 [XWiki initialization] ERROR c.x.x.XWiki - Failed to initialize mandatory document com.xpn.xwiki.XWikiException: Error number 3202 in 3: Exception while reading document [xwiki:XWiki.WikiMacroParameterClass] [...] Caused by: com.xpn.xwiki.XWikiException: Error number 3301 in 3: Exception while switching to database xwiki [...] I'm so confused ... what did i do wrong ?!
