Port Labor dates EB3 to EB2

[nyc_dude]

Hello, I have/had EB3 labor under old processing with previous company dated 11/2004.
Now am with current company new labor dated 4/2008 and I140 approved on 7th year extension.

Can I port EB3 labor date 11/2004 from old company to current company EB2 labor dated 4/2008. If so, how is the best possible way.

Thanks
