I need a question answered about my iMac.

Hi Reddit, I have a Late 2009 A1312 27 inch iMac. Recently the logic board died in it and i bought another one, Will my old hard drive with opencore on it still work with the new logic board? its the same model number as the old one. literally the same board. So will it work? If not, I bought a hard drive on ebay with high sierra on it and im willing to reinstall open core if needed. Thanks.
