Migrating rule assets in Drools workbench 6.1 from DEV to other environments

We have a setup where Drools workbench is deployed in all of our environments with their own local GIT repositories on them. I wanted to know if there is any way I can export and import the rules and decision tables from one git repo in dev environment to similar repo in test environment without causing broken links (along with it some broken hearts:) ) Note that this is the first time organization is using Drools workbench and lot of us here too are novice users on this tool.

What is the migration process in general when using Drools workbench?
