How to reuse testcases

Zephyr's organization of test cases in its Test Repository application allows for easy reuse of testcases. The availability of every single testcase across all releases/iterations and across all projects within Zephyr make it easy to find an individual testcase, a group of testcases, a sub-node or a node anywhere in the system.
 
Once they have been located, they can be dragged and dropped into the appropriate location in the Local Tree of the release/iteration being worked on.
 
For example, you can copy over all the Functional testcases from a previous release and drop them into a Regression phase of a new release to automatically reuse those testcases. You can do this while in the Local Tree of "Version 2.0", navigate down to "Version 1.0" testcases in the Global Tree, find the "Functional" test node and drag and drop it into the "Regression" phase of "Version 2.0". The entire structure is copied over including testcases.
