Replace gear linkage cables - difficult?

Given my cars mileage (91k) and the fact that I understand the gear linkage cables can stretch, I was going to replace them - any idea how tricky this is? Is there any adjustment in the cables rather than just replacing them? I do have some spares from a low mileage car but adjustment would probably be easier than replacement.

TIA!
