Lab Validation of UV spectrophotometer

Can anyone tell me what validation needs to be done when transferring analytical methods from one UV to an identical model with new software

We have the same question.

I found this reference:

intermediate precision only.
Day 1, analyst 1, equipment 1 = 6 spl prep

Day 2, analyst 2, equipment 2 = 6 spl prep

find RSD of 12 result (%). acceptance crtiteria < 2%RSD
