I already used differents versions of drools like you describe without big problems.
The only real problem is if you use some 5.2 new features that can't be handled by previous runtimes versions. The inverse is more safe: guvnor, which is the rule editor, having lower version than runtime.

But let me turn the question : what prevent you from upgrading all your components to the last version ? (and I recommend you to pass to 5.3 which has some important bug fixes on guvnor).

Hi guys ,
I am new to this Drools.

I have one small doubt,

Is it mandatory to have all equal versions While executing Drools-Guvnor Applications ?
For example:

Binaries and Dependencies of Drools- 5.1.1
Drools_Eclipse Plugins & Features-5.1.1
Drools Guvnor (.war)-5.1.1


Currently  I used following version:

Binaries and Dependencies of Drools- 5.0.1
Drools_Eclipse Plugins & Features-5.0.1
Drools Guvnor (.war)-5.2.0

Is this fine? or Shall I install all of these of equal versions.
Please help me.



Thanks and Regards
