  We consider the problem of obtaining higher order in regularization parameter
$\epsilon$ analytical results for master integrals with elliptics. The two
commonly employed methods are provided by the use of differential equations and
direct integration of parametric representations in terms of iterated
integrals. Taking non-planar elliptic vertex as an example we show that in
addition to two mentioned methods one can use analytical solution of
differential equations in terms of power series. Moreover, in the last case it
is possible to obtain the exact in $\epsilon$ results expressible either in
terms of generalized hypergeometric or Kamp\'e de F\'eriet functions
