Реализация reserve для вектора

Правильно я сделала функцию?

 template<typename T>
 void Vector<T>::Reserve(size_t capacity)
 {
    if (mCapacity >= capacity)
      return;
    if (mCapacity <= capacity)
    {
       T* result = new T[capacity];
       for (decltype(mSize) i = 0; i < mSize; ++i)
          result[i] = mCapacity[i];
       delete[] mCapacity;
       mCapacity = result;
    }
}

Переделала

 template<typename T>
 void Vector<T>::Reserve(size_t capacity)
 {
    T* result = new T[capacity];
    mCapacity = capacity;
    if (mCapacity <= capacity)
    {
       for (decltype(mSize) i = 0; i < mSize; ++i)
           result[i] = mVector[i];
       delete[] mVector;
       mVector = result;
    }
 }
