Frame swap?

Frame swap?

I went splits on a CX500 with my dad, as a restoration project to work on together. The rear of the frame had been cut, and a new section welded in by the previous owner – not very well I might add.

I’ve spotted a couple of frames for sale on adverts, and was thinking of getting one of them to use instead. The question is, do I transfer everything onto the new frame & write off the frame I have as scrapped, or is there a way to change the frame number on the logbook I have? Only thing I can see on the motortax forms is for an engine change
