Query

Hi. I have two queries. Pls help me:
1. The UAN is allotted to me from my current employer.Now if I leave the organization and join any new one can i withdraw my P.F of the previous organization just like I earlier did before adopting the new system of UAN by EPFO? or, is it compulsory to transfer the P.F balance of old organization?

2. Suppose I have left my current organization without getting any new job and after 2 months or so, I get a job in a new company. Now, can my new company track the exit date of previous employment with the UAN?
