Name Of The School On EPF Challans And Migrate The Employees Of Trust To School?

I have a trust which is registered under EPF. The trust contains a single school. I want to add this school as a unit so that EPF Challans may be in it's name. But while adding unit there is a requirement of no of emloyees, and the employees of the school are already registered with the trust.
How can I get the name of the school on EPF Challans or how can I migrate the employees of trust to school???
Kindly suggest.

EPF registration is issued exact as per PAN card details. it is pan based registration
you can generate a sub code, but there would be minimum charges payable monthly for principal code (75+25)

If I will take a sub code, I will have to comply for both the units.
And it will occur extra administrative charges.
Suppose I added a sub code then what about the members which are already registered with the trust, left or what?

they will leave the 1st code and will join sub code,
better you can visit the EPFO office, and visit ......establishment section for discussion, they are always helpful to resolve these issues
