Trending @Infosys; PF QUERY DETAILS

I recently joined here i just have few queries on how to transfer my pf here in my current organization infy. I previously worked for hcl and I got to know that it is difficult to transfer from hcl since hcl maintain its pf in a trust and they did not provide me with the UAN number so what is tha actual procedure here ? If anyone knows please let me know.
