Dear Sharma,
Yes it can possible you can transfer through online from your logon portal , if not you can transfer through off line not required both employer signs on form -13

I have tried online but there is error "No previous employment details found against this UAN".

Dear Mr. Sharma,
Request your previous employer to put "date of exit" on EPFO portal as per your record and contribution details. Thereafetr you will find previous employment option to transfer your fund to your recent employer.

Previous employer not ready to update Date of Exit , that why i am apply for offline process but there is 1 query for offline PF transfer if Form attested by Present Employer and send to Regional PF Office then Transfer Possible or Return for Previous Employer Attestation.
Please Reply

Dear Mr. Sharma, you can check the service details of the both the employer by login in to the UAN portal. There if the DOE of the previous employer is empty (NA), then contact the previous employer to update the DOE, then only you can transfer through online.

Dear sharma,
If you done by your present employer then no problem they will submit in pf office after that your pf amount will be transfer from previous company to present no need no contact to your previous company.

Dear Sharma, No problem. Fill the form 13 getting authentication by present employer authorised person and submit the same into your current relevent PF office.
Or write a mail to the PF commissioner citing your problem and intention of your previous employer cc to current PF commissioner and previous company too.
