Has anyone attempted to change a Benefit Record Number on an employee after their hire, few payrolls

Benefit Record number was accidentally entered as 1 instead of 0 and after a few payrolls and missed benefits vendor files , it was observed the root cause was the benefit rcd #. Everything in the system is coded for Ben Rcd # = 0

Is there a way to simply update the Ben Rcd # to 0 on Job Data, Run the Maintain Primary Flag/Reset Prim. Flag process, Re-process the benefits ?

What would happen to the Deduction Balances, would the balances against ben rcd 1 be wiped out.

Has anyone done something like this in the past.

WE are about to begin testing but thought of asking here, since most knowledge articles recommend against it!
