Should the Axis Resolver Values on the label & the Motor Calibration Offset Values be same?

Options
I have noticed that the Motor Calibration offset values displayed in the pendant is not same as the Axis Resolver values in the label pasted on the arm but at the same time the status of the robot and controller memory is shown as Valid. After  that, I was trying to set up a new system from my backup from a different robot but the system goes into system failure after I restore the system from my back up. I have changed the relevant parameters in MOC.cfg such as Serial Number and the Calibration offset values.  In the error log, I have errors like "Unsync due to CFG data", " Joint not Synchronized" and "Robot Memory Data Difference". I am unable to proceed further because of the problem.
