So I just set up two clusters here. One that is running pure 3.0.x and another that is running pure 3.1.x with their respective web frontends reporting the cluster data. Then I crossed the two clusters by declaring new data_sources in the gmeta.conf file of each gmetad/web frontend servers. I can hit the web frontend of either server and view the RRD graphs for both clusters. In other words, the 3.1.x gmetad and frontend is able to acquire data from a 3.0.x cluster and a 3.0.x gmetad and frontend is able to acquire data from 3.1.x cluster. So the cluster by cluster migration from 3.0.x to 3.1.x should work just fine.
