Moving a music system from one room to another is an interesting process. Sometimes the new space will lack the life, sense of space, or the low frequency warmth of the old room. Or the music may sound blurry and poorly defined.
Will performing acoustic measurements in the new room provide an accurate guide as to the treatment required? Well, yes and no. Yes, it will identify frequency response issues and reverberation times that need to be addressed in order to improve the accuracy of the room. And no, if the aim is to reproduce the acoustics of the old room. The original room may have had significant acoustic issues that the listener found appealing, for example, exaggerated very low frequencies. This can make kick drums sound huge and give very low frequencies in movie soundtracks extra impact. Obviously, for music production applications, accuracy is paramount.
