[xwiki-users] Migration from 7.0.1 to 8.2.1 issues.

To migrate my XWiki from 7.0.1 to 8.2.1, I followed those steps : cd /glassfish4/glassfish/domains/domain1/applications/xwiki-enterprise-web-7.0.1/\r tar -jcvf /backup/xwiki.tar.bz2 /glassfish4/glassfish/domains/domain1/applications/xwiki-enterprise-web-7.0.1/WEB-INF/hibernate.cfg.xml /glassfish4/glassfish/domains/domain1/applications/xwiki-enterprise-web-7.0.1/WEB-INF/xwiki.cfg /glassfish4/glassfish/domains/domain1/applications/xwiki-enterprise-web-7.0.1/WEB-INF/xwiki.properties /glassfish4/glassfish/domains/domain1/applications/xwiki-enterprise-web-7.0.1/WEB-INF/classes/logback.xml /glassfish4/glassfish/domains/domain1/applications/xwiki-enterprise-web-7.0.1/WEB-INF/observation/* mysqldump --add-drop-database --all-databases > /backup/xwiki.sql Then I restore dit back on the next server : mysql -e "SET FOREIGN_KEY_CHECKS=0;" mysql -e "CREATE DATABASE IF NOT EXISTS xwiki DEFAULT CHARACTER SET utf8;" mysql xwiki --user=root -p < xwiki.sql mysql -e "SET FOREIGN_KEY_CHECKS=1;" reboot I set the right options in the xwiki.cfg but I got this problem after the migration... :( http://pastebin.com/cS8Th8c4 Anyone can tell me what am I doing wrong ? Should I update to an older version before upgrading to 8.2.1 ? Sebastien
