And that affects the server, but not (directly) clients. > The rule of thumb has always been to support one major version backwards, so > a 2.7 server should in theory support 2.6 clients, and 0.25 clients less so. > YMMV, as there really isn't a strict guarantee of backwards compatibility in > any case. I was certain that PuppetLabs's commitment was that clients should continue to work with servers up to *two* major versions newer, thus 0.25 clients should still work with 2.7, but probably not with 2.8.

On the other hand, if the ultimate target is 2.7 (and later), then it may be worthwhile to bite the bullet and do it all at once, instead of going through the whole process twice. I am confident that the larger jump would be more work than the smaller, but doing it in two separate jumps would surely be the most work of all. As for risk, I think that's much more tightly coupled to the distance you move in version- number space than to the path you take to get from here to there. Personally, I would be inclined to jump straight to 2.7, but Brian is exactly right that you should evaluate your options in light of your own environment and requirements.
