We study half-BPS flows in gauged minimal 7d supergravity featured by an AdS3× S3 slicing of the metric, supported by a dyonic three-form field. We first present a novel strategy for analytic integration of the BPS equations, which makes use of the integrals of motion. Subsequently, we discuss the suitable choice of integration constants that gives rise to smooth geometries. These flows are asymptotically locally AdS7 in their UV limit, while their IR geometry is AdS3× ℝ4. We then discuss their uplifts to 11d and massive IIA supergravity and observe that they describe one-parameter deformations of their AdS7× S4 and AdS7× S3 vacua, respectively, their holographic interpretation being as conformal defect CFT2's within the corresponding dual SCFT6's. We conclude with the computation of the holographic central charge, by focussing on the M-theory interpretation.
