eb3 to eb2 porting same employer

[jay76]

Hi -

I have been with my current employer for 5+ years. I do have 5 years prior experience , before joing to my employer. 3 years back my Job duties did change more than 50% from my previous filing of EB3. My status is I140 approved with priority date in Feb 2004

I have only Bachlors(4yrs). Please let me know if my current employer can file in EB2 now and port my EB3 priority date? .Thanks

Please help
