We study evolution of the gluon transverse momentum dependent (TMD) operator using rapidity factorization approach. The obtained rapidity evolution equation is valid at all values of the gluon longitudinal momentum fraction x. At small values of x we apply the shock-wave approximation, while at moderate-x we use the light-cone expansion formalism. The equation describes transition between linear evolution at x ~ 1 and non-linear one at x << 1.
