EB# to EB2 after applying for I 140

[indiatous]

My GC is applies under
EB3 (RIR)
I140 is under process

I have 10yrs experience in my field of work and holds Masters degree in same. At the time when the GC was applied my company said that they don't prefer to apply under EB2 so we got to apply under EB3. Since now the company policy has changed. So can we apply under EB2 RIR.? If Yes then what will happen to present I140 and EB3 case of mine. And when applying for EB2 do i need to go through LC again or not? what if EB2 case is rejected will i be able to keep my Eb 3 or not. And during whole process what will happen to my PD?

Please help.
Thanks for the comments
