  We study the effect of non-Abelian T-duality (NATD) on D-brane solutions of
type II supergravity. Knowledge of the full interpolating brane solution allows
us to track the brane charges and the corresponding brane configurations, thus
providing justification for brane setups previously proposed in the literature
and for the common lore that Dp brane solutions give rise to D(p+1)-D(p+3)-NS5
backgrounds under SU(2) NATD transverse to the brane. In brane solutions where
spacetime is empty and flat at spatial infinity before the NATD, the spatial
infinity of the NATD is universal, i.e. independent of the initial brane
configuration. Furthermore, it gives enough information to determine the ranges
of all coordinates after NATD. In the more complicated examples of the D2
branes considered here, where spacetime is not asymptotically flat before NATD,
the interpretation of the dual solutions remains unclear. In the case of
supersymmetric D2 branes arising from M2 reductions to IIA on Sasaki-Einstein
seven-manifolds, we explicitly verify that the solution obeys the appropriate
generalized spinor equations for a supersymmetric domain wall in four
dimensions. We also investigate the existence of supersymmetric mass-deformed
D2 brane solutions.
