armature from previous model to new one?

Hi,

edit: ok nevermind, i had to keep the exact dimensions, and then scale the character.

[I used an armature from a previous model, the new model is a bit bigger so i moved the bones a bit to match the new model in Edit Mode, but when I go back to Object Mode, it goes back to its original position. Would you know how i could keep the new settings for the new model?

Thanks a lot]
