[Aircraft X] was on an IFR flight to ZZZ1 on [Airway1] at 9;000 ft. There was another aircraft on [Airway2] also landing ZZZ1 just handed off to me also at 9;000 ft. The adjacent sector asked me if I would like [Aircraft X] at a different altitude and I gave them 8;000 ft.; which they complied with. Upon further review that was below the Minimum Vectoring Altitude of 8;600 ft. and [Airway2]'s Minimum IFR Altitude of 8;400 ft. I should have been more aware of the Minimum IFR Altitudes along [Airway2].
A Center Developmental reported they issued a control instruction to an aircraft through another controller that placed it below the Minimum Vectoring Altitude and Minimum IFR Altitude.
