I refinanced a rental property and have mortgage points that I can add as an asset, but what do I do with the points asset from the original loan?

The question kind of says it all. I have rental property that I purchased in 2013 and I'm still depreciating the points from the original loan as an asset. I refinanced the property last year so now have a points asset - what do I do about the old one? Do I just say it was taken out of service or do I just delete it?
