Obtain din for converting firm to llp

Hai All.....

In MCA it is seen that 'Spice' should be used for obtaining DIN for a Director in new company, however when I viewed the form its a single form for entire Incorporation Procedure. DIR 3 is said to be used only for new directors in existing Company. How to obtail DIN for Directors for converting a firm to LLP. Also Other than Form 17, Form 2 and Form 3 are there any other requirements for conversion?? 

Thanks in Advance...
