Do you mean increase the size of the disk volume? no i think they mean change the flavor to increase or decrease the cpu/ram
this type of virtial vm scaling has been requested in the past but it really non tivial to implement so we have never approved a spec to add support to this to nova. if they are refering to voluem resize that should be possibel live if you are using cinder and not novas built in rbd support.
It is possible to increase volume sizes live with ceph storage.
