Spelling mistake in Eb2-140 - applying for EB1 140 - should it be corrected prior?

[raj_lt]

Hi all,
I have a EB 2 i140 approved with a priority date in 2012. My company is trying to apply EB1 -i140 now. I just now noticed that there is a typo in my first name in the EB2 i140 approval notice. So should i first apply for correcting it and then apply for EB1 or i can apply in EB1 with the right spelling and attach the previous approved 140 with Alien numbers mentioned?
I want to port the priority date and hence the question to know the steps here. Please advise
