Employee switch to RP0001 from RP0002 set up

Hi, 

If I have an employee switching from RP0002 to RP0001 payroll account, do I create a new employee account for him or just change it on his current profile. I'm thinking ahead to T4's where this would cause an issue for my two account balances at the end of the year if I use his current profile. 

If I should have made him a new profile and already issued one cheque just by changing him to the new RP0001, how can I go back and fix it so it will have the two separate payroll accounts?
