It's worth noting that braces are usually placed in pairs. Basically, the purpose of bracing is to withstand intermitant transverse loading. The stress of raising is one example. Wind and snow are others.

Wind loads are hard to predict, both in strenth and direction. By placing braces in opposite "pairs", one works to resist the wind from one direction, while it's pair rests. When the wind switches direction the opposite occurs.

In many early barns, braces were not pegged. This lack of pegs indicates the early framer's understanding of the work a brace does being resisting a force by going into compression.

In a nutshell, moving a brace to keep it paired is the best solution. If you have to remove one, it's likely you should remove it's pair also.

Having an engineer look at the drawings is of course the most dependable solution.
