Parcellation of BrainSpan LMD into Desikan Killiany atlas

Summary of what happened:

Hi, I want to assign the 34 Desikan Killiany labels to the ~300 anatomical labels given n the BrainSpan LMD dataset. Has anyone done that or recommendations how to do it? I struggle with anatomical precision to map fetal to adult regions.
Thank you!
Best, Melissa
