For reductive groups $G$ over a number field we discuss automorphic liftingsfrom cuspidal irreducible automorphic representations $\pi$ of $G(\mathbb{A})$to cuspidal irreducible automorphic representations on $H(\mathbb{A})$ for thequasi-split inner form $H$ of $G$. We show the existence of cohomologicalnontrivial weak global liftings in many cases. A priori these weak liftings donot give a description of the precise nature of the corresponding localliftings at the ramified places and in particular do not characterize the imageof the lift. For inner forms of the group $H=\mathrm{GSp}(4)$ however weaddress these finer details. Especially, we prove the recent conjectures ofIbukiyama and Kitayama on paramodular newforms of squarefree level.
