Aganagic and Okounkov proved that the elliptic stable envelope provides the pole cancellation matrix for the enumerative invariants of quiver varieties known as vertex functions. This transforms a basis of a system of q-difference equations holomorphic in \boldsymbolz with poles in \boldsymbola to a basis of solutions holomorphic in \boldsymbola with poles in \boldsymbolz. The resulting functions are expected to be the vertex functions of the 3d mirror dual variety. In this paper, we prove that for the cotangent bundle of the full flag variety, the functions obtained in this way recover the vertex functions for the same variety under an exchange of the parameters \boldsymbola ↔ \boldsymbolz. As a corollary of this, we deduce the expected 3d mirror relationship for the elliptic stable envelope.
