Person number correction

Summary:

Person was hired by missing one zero in the Person Number, whereas Assignment number is correct.
Person Number: 1001234
Assign Number: E10001234
Person number need to correct to 30005381 from 3005381

We received steps as we can switch the Configuration of 'Person Number Generation Method' to Manual and get the person number corrected. Once person number is corrected , switch back configuration to 'Automatic Upon Final Save'.

Need to understand this impact of changing the Configuration here. Will it affect the 'Initial Person Number' ?

Also do we need to run any process after this configuration change?
