although we bumped the major number in the 2.5.x -> 3.0 transition, we took care to not introduce incompatible changes to the core metrics framework. In short, I see no reason why a 3.0.4 gmetad should not be able to query 2.5.x gmond data. It should even be possible to have a 3.0.4 gmond listen to older gmonds. Of course, you are limited to multicast until you have replaced all gmonds. Just try it out.
