  A group $G$ is called subgroup conjugacy separable (abbreviated as SCS) if
any two finitely generated and non-conjugate subgroups of $G$ remain
non-conjugate in some finite quotient of $G$. An into-conjugacy version of SCS
is abbreviated by SICS. We prove that if $G$ is a hyperbolic group, $H_1$ is a
quasiconvex subgroup of $G$, and $H_2$ is a subgroup of $G$ which is
elementwise conjugate into $H_1$, then there exists a finite index subgroup of
$H_2$ which is conjugate into $H_1$. As corollary, we deduce that fundamental
groups of closed hyperbolic 3-manifolds and torsion-free small cancellation
groups with finite $C'(1/6)$ or $C'(1/4)-T(4)$ presentations are hereditarily
quasiconvex-SCS and hereditarily quasiconvex-SICS, and that surface groups are
SCS and SICS. We also show that the word "quasiconvex" cannot be deleted for at
least small cancellation groups.
