[rules-users] ILog JRules to Drools Migration

Has anybody ported a large number of rules from ILog JRules to Drools? If yes, I'm very much interested in the following information: - how did you do the migration (automatic vs. manual)? - if automatic, how exactly (AST to AST transform, custom JRules parser, ...) - which features of JRules did you use (decision tables, rule tasks, ...)? - which migration issues did you encounter? how did you solve them? - ... Thanks Simon
