I've just verified, and the 'change title everywhere' checkbox is still there when moving a topic (move topic is at the very bottom of the thread, only OP can see that option).
Check the change title checkbox, then check to change it everywhere, then maybe move it in the same section (so no move, just rename). If it is not allowed to move inside the same forum section (rename), then move it with rename to some other forum section, then immediately move it to the section where it was originally.
Note how the title from my previous post was not inherited in this reply, I guess I was wrong about that.
