[rules-users] Running drools 4 code using drools 5 jars

Hi, I have written some code using drools 4 jars. Now as drools 5 is launched, I want to migrate my existing 'RuleBase' (drools 4) to 'KnowledgeBase'(drools 5). 1. Can I/Should I use RuleBase, PackageBuilder, ExternalSpreadSheetCompiler using drools 5 jars?? I can use these classes as they are present in drools-compiler-5.0.1.jar Is anybody facing the same issue? Please let me know if somebody has a solution for this. Thanks & Regards, Nikhil MASTEK LTD.
