Took responsibility for ZZZ's airspace at XA:00 Z. Aircraft X originally requested an ILS to a runway that was unavailable after the tower closed. I was R side with no D side controlling a mid configuration scope. Aircraft X set up for ILS Z runway XX ZZZ. Crossing restriction for the IAP (Initial Approach Point) was 1;700 ft. I issued my MVA of 'cross IAP at or above 020; cleared approach...' ZZZ's airspace is unfamiliar due to the little amount of time ZZZ1 is responsible for it; however; the knowledge and rules are still understood. An MSA of 030 was located between the aircraft and the IAP at the time of the clearance. Once the target flashed MSAW; I climbed Aircraft X to 030 for a minimum safe altitude and restated clearance to now 'cross IAP at and maintain 030...' Aircraft X continued the approach; reported inbound on approach; and canceled IFR in the air after ZZZ was reported in site. Continued experience with approaches involving unfamiliar airspace ownership.
We were getting ready to combine sectors to the Mid configuration. I was sitting at the scope where the positions would be combined so I called the supervisor to make the combination entry. As I began to look at the traffic I would be getting from the other sector I saw that and MSAW warning was flashing on Aircraft X. It seemed odd to me so I asked the other controller if Aircraft X was on an approach. They said Aircraft X had been cleared so I asked if Aircraft X had passed the IAF. Aircraft X had not so I told the other controller to climb the aircraft; which they did. I took track control of Aircraft X when he reached 030 and we continued the sector combination.I can not make any recommendations because I only noticed the situation and do not know any of the events that led up to the event.
Controllers reported while accepting airspace of a closing facility; an aircraft entered a higher MVA.
