Khalid, what you can do is to note how much the higher energy (at energy E1) feature is shifted from what you think it should be (let's say by the amount of D eV), provided that you fixed the lower energy point to what you wanted (say, E0). Then, you should transfer the data into a spreadsheet and apply linear scaling:
E --> E0 + (E-E0)*D It will ensure that in the range between E0 and E1 the data are linearly stretched or compressed, depending on the sign of D.

I have a Ni foil spectrum as a function of time. The edge can be set at 8333.0 eV, and I want to to assign higher energy to a known feature in the Ni scan.
