I am hardly an expert on arm stuff, but I have run into this
particular point (v6/v7 differences) and as best as I recall, while
there are quite a few things in v7 that aren't in v6, there isn't
anything in v6 that's not in v7 and only a couple things that are
randomly incompatible, and only in minor ways.

At least in the instruction set, and if you aren't trying to use
thumb. I'm less certain about control registers.
