Lightroom from XP to Mac

[DeepSpring]

Hello so I just got myself a new mac book. I have a fairly large library already in my old version of lightroom fro my pc. I have lightroom now for the ma and I was wondering if there is a way for me to transfer everything over so I can still save all of my edits and everything. I do have an external drive so the physical aspect of transferring isn't a problem.

Thank you
