귀찮아서 그냥 몽고 쿼리로 넣어버림

let cursor = db.lectures.find();
while (cursor.hasNext()) {
  let document = cursor.next()
  const class_time_json = document["class_time_json"].map((json, idx) => {
    let start = json["start"];
    let len = json["len"];
    let end = start + len
    let startHour = Math.floor(start + 8);
    let endHour = Math.floor(end + 8)
    let isCustom = false
    let islen30 = Math.floor(len) !== len
    const startTime = startHour === start + 8 ? `${startHour}:00` : `${startHour}:30`
    const endTime = endHour === end + 8 ?
      (islen30 ? `${endHour - 1}:45` : `${endHour - 1}:50`)
      : (islen30 ? `${endHour}:15` : `${endHour}:20`)
    return {
      ...json,
      start_time: startTime,
      end_time: endTime
    }
  })
  const real_class_time = class_time_json.map((j, idx) => {
    return `${"월화수목금토일"[j.day]}(${j.start_time}~${j.end_time})`
  }).join("/")
  db.lectures.updateOne({_id: document["_id"]}, {
    $set: {
      class_time_json: class_time_json,
      real_class_time: real_class_time
    }
  })
}

let cursor2 = db.timetables.find().sort({updated_at: -1});
while (cursor2.hasNext()) {
    let documentTT = cursor2.next()
    let change = documentTT["lecture_list"].map((document, idx) => {
        if (document["class_time_json"] !== null && document["class_time_json"].length !== 0) {
