In my experience, downgrading with freebsd-update works fine, although I only went back from 10.1 to 9.3, but arguably that’s a much bigger jump. We’ve done it on around 40 machines over ssh. You just have to skip the initial reboot, in order to stay in the new kernel. Here is a blog post I wrote about it: <>

I can’t guarantee that going back from 10.2 to 10.1 will work too; there might be problems, but if you try it, let me know your experiences and I’ll update the post.
