In this paper, the pressure dependence of the magnetic and superconducting transitions and that of the superconducting upper critical field are reported for $$\mathrm{CaK}{({\mathrm{Fe}}_{1{-}x}{\mathrm{Ni}}_{x})}_{4}{\mathrm{As}}_{4}$$, the first example of an Fe-based superconductor with spin-vortex-crystal-type magnetic ordering. Resistance measurements were performed on single crystals with two substitution levels $(x=0.033,0.050)$ under hydrostatic pressures up to 5.12 GPa and in magnetic fields up to 9 T. Our results show that, for both compositions, magnetic transition temperatures $${T}_{\mathrm{N}}$$ are suppressed upon applying pressure; the superconducting transition temperatures $${T}_{\mathrm{c}}$$ are suppressed by pressure as well, except for $x=0.050$ in the pressure region where $${T}_{\mathrm{N}}$$ and $${T}_{\mathrm{c}}$$ cross. Furthermore, the pressure associated with the crossing of the $${T}_{\mathrm{N}}$$ and $${T}_{\mathrm{c}}$$ lines also coincides with a minimum in the normalized slope of the superconducting upper critical field, consistent with a likely Fermi-surface reconstruction associated with the loss of magnetic ordering. In conclusion, at $$p{\sim}4$$ GPa, both Ni-substituted $$\mathrm{CaK}{({\mathrm{Fe}}_{1{-}x}{\mathrm{Ni}}_{x})}_{4}{\mathrm{As}}_{4}$$ samples likely go through a half-collapsed-tetragonal phase transition, similar to the parent compound $${\mathrm{CaKFe}}_{4}{\mathrm{As}}_{4}$$.
