Pension Fund not transfer from old account to new account

Hi, Is there a way to transfer Pension Fund from previous employer to the current employer? In all my previous PF transfers, i've received only the PF amount. I am not sure where do they keep that pension amount. Any help on the following points will greatly appreciated. i) Can we really transfer the Pension fund from one account to another? ii) In case if the PF account was settled long back, are we still eligible to withdraw/transfer our pension fund associated with that PF account? iii) Can somebody please help me with process of withdrawal/transfer Pension fund( like different forms) .
My previous company total years is 9.
Thanks in advance!!!

if UAN is same in both, then no need to worry, it is accumulated in UAN not in member's ID
