We are working to develop a full pipeline in our environment for testing new binaries. We are working to setup a pre-prod environment so we can test out new clusterfuzz updates as well as we develop this pipeline. We want to make sure that all the crash stats and history of our current production clusterfuzz is in preprod. Is there a way to migrate all the data from one clusterfuzz to another? If not what are the important data points that we need to copy over?
