EE with LMIA. Offer of Employment from current employer

[evanstrip]

Hi,

I recently got LMIA from my employer that I have been working for 2 years.
With the LMIA point, I recently got EE invitation.

Now I need to submit "Offer of Employment"
For sure I got job offer 2 years ago.
Can I just use the offer letter that I got 2 years ago?
Or do I need to request another offer letter with current position/payroll?

Thank you
