Regarding PF Account Linking To UAN

Dear All,
We have a problem with one of the employee, PF account linking to UAN.
1. The employee did not provide his/her UAN which was previously generated by his/her previous organization.
2. The transfer amount is already been reflecting in New UAN, but not the previous PF account number.
We want to add a PF account number to new UAN, how can i add as a employee or a employer. Kindly let me know how to go about it.
Regards,

Dear Akhila,
You can simply ask your employee to feel PF transfer form. Which will shift all his money from OLD to NEW account.
