我们可以在同一个应用程序（drools-spring）集成应用程序中并行运行drools 5和drool 6吗

我有基于drools 5规则引擎的现有应用程序，需要迁移到drools 6，但我们不能一次性完成，即我们必须分多个阶段完成。 所以我的要求是我想在同一个应用程序中支持Drool5和Drool6并行执行

For that i  have created sample poc 
1) Created drools spring integration application having both drools 5 and drool 6 spring integration configuration files .

For Drools 5 :

2) Added maven depencies for both drools 5 and drools 6 by changing drools 5 standard jar's group id and arctifact id in order to avoid version overwite 

3) With above  configuration drools 6 working fine but while loading drools 5 spring configuration file getting error

Your help will be appriciated .

1) Can we support drools 5 and drool 6 in parallel in same classpath 

2) If yes is there any way or any one have any sample 

Thanks and regards 
Sri

为此，我创建了示例poc
1） 创建了drools spring集成应用程序，该应用程序具有drools 5和drool 6 spring集成配置文件。
对于口水5：
****口水6:**
2） 通过更改drools 5 standard jar的组id和arctifact id，为drools 5和drools 6添加了maven依赖性，以避免版本过度使用
3） 以上配置drools 6工作正常，但加载drools 5时，弹簧配置文件出错
