How to recall parameters of the acquisition method of an older chromatogram

Hello. Recently we started working in our laboratory with a GC/MS 5977C and the mass hunter software (acquisition, quantitative and qualitative suites). Iam wondering if and how we can recall the parameters of the acquisiton method of a chromatogram at the day of acquisition. The point is if a method has changed, can we recall the parameters as the were in previous versions with which older chromatograms have been acquired? Thanks
