Import an exhibit with import api?

Hello,

A class exhibit was accidentally deleted and I’m trying to restore it. Our IT department was able to pull a back up copy of our install before the delete happened so I have another copy of our Omeka install on a new server to copy from temporarily. What is the best way to import just the one deleted exhibit? Can I do this with the import API plugin? I have that installed but it looks like it copies the whole site. What if new things were added to the original site while the back up site was being generated? Will those new items/exhibits/collections be retained?

Thanks!
