If you're using Songtrix, you can lay all your chords out in the Chords Track and then use Track-Transpose to adjust all of them together (and also any melodic parts that you have created).

if you are transposing chords and want to go up from F to G say, just add a full step to each chord and you are done. If the chords are F,Bb, and C7, play G,C and D7. Done
