It's "doable", in that many of us have indeed upgraded through those control points with source, but it can't necessarily be done in one step. Is it worth trying to do in multiple steps? Maybe not: you'll almost certainly want a larger root partition, and may very well want to change to UFS2, both of which mean that you're going to have to dump to backup, repartition, reformat and restore at some stage (and that stage is one of the intermediate stops, because you don't have UFS2 in 4.9). So: you're going to need to be able to boot from the 7.2 (or whatever) kernel+fixit combination to do the reformat anyway, so why not go the whole hog and reinstall directly to 7.2 (or so) at the same time? That's what I did when I hit the UFS2 barrier, and I'm otherwise a died-in-the-wool source upgrader. If you're having trouble getting 7.1 to boot from CD, then try 7.2 or otherwise sort out that problem, because not having a bootable CD fallback position is not a comfortable place to be, anyway.
