[rules-users] Migration from Drools 2 to latest version

Hi all, I'm a newbie with Drools and currently I have a project which uses drools 2 which should migrate to a newer version. I've noticed a lot has evolved since 2006, thus I have few questions I did not find an answer: . use Drools 4.0.7 or 5.0? . unfortunatelly the XML rule definition translation from 2 to 4 (_http://www.jboss.org/community/docs/DOC-9598_) did not work for me. Did anyone use this solution? Are there any online examples available? . where can I find simple examples using the Drools workbench besides the screenshots in _http://www.jboss.org/drools/featuresandscreenshots.html#screenshots_ ?_ _ Best Regards, J.Mouta
