Move favorite post count from one site to another

I made a duplicate of my site to work on while leaving the original site untouched so my visitors would not be disturbed by an under construction time.

The changes have ended up so detailed that it’s now much easier for me to delete the original site and replace with the updated version.

The problem is, that in the interim, the favorite posts plugin has been used so many times that the difference between the old count (on the copied and updated site) is now so big compared to the original site (by 30,000 in some posts – I never expected it to be so popular).

How do I export the data from the original site to the new one so that I don’t lose the counts?

Thanks in advance.
