[rules-users] Guvnor -> Best Practices for Changes in Production / DEV Environment

Hy all We're having the following Environments: - DEV (dev site) -> Guvnor WebApp: Used for defining the rules and exporting the xxx_rules.pkg during development. -> XXX WebApp: Our WebApp which uses the xxx_rules.pkg for executing the rules, for testing during development. ----------------------- - PROD (customer site) -> XXX WebApp: WebApp in production. - CHANGE (customer site) -> Guvnor WebApp: For changing/adding rules by customer itself and exporting the changed xxx_rules.pkg by the customer -> XXX  WebApp: For Testing the changed xxx_rules.pkg by the customer We're using Drools Guvnor (5.5.0 Final). Now the question: - How to deal with changes of the customer to the rules? We need those changes in our dev-guvnor too... - So how to deal with the following scenario: -> Customer changes a rule in Guvnor on the CHANGE Environment and tests the rule on his CHANGE Environment -> After successful tests, he overwrites the xxx_rules.pkg in the PROD Environment -> In the same time, the development team is adding new rules or changing existing rules on the DEV Environment (for example for Bugfixing or when adding new features to the WebApp) -> After successful testing on DEV-Site, we want to deploy the new Version of our WebApp (and xxx:_rules.pkg) to the Customer (CHANGE and PROD). But when we just build the xxx_rules.pkg in our DEV-Guvnor and overwrite the xxx_rules.pkg from the customer, the changes from the Customer are lost. So how can we get the changes to the rules from the Customer to our DEV-Guvnor? The only way we now, is to export/import the whole repository. But with that, the changes (updated/created rules) from our DEV-Guvnor are overwritten... How to deal with such a scenario? Is it possible to import/export single rules instead of the whole repository? Thanks for your help, Peter
