Import LR Project from External Drive w/ different Ircat Files

[rafaeld40474899]

I performed a recent erase and install on my Mac (Sierra OS). I kept all of the Ircat files on an external drive. However, I missed an update. But I have a solution.

Project 01: Has all of the photos and Ircat files on a portable external drive. Some of the photos were edited and names assigned to faces. I imported the project onto my main external HD when I returned home.

Project 02: Resides with all of the other LR projects on my main HD at home. It has not been re-imported into LR since the erase. It was originally imported from Project 01(see above), and then had additional edits and names assigned to faces.

My questions:

(1) What information does Project 02 contain, if any?

(2) If there are no names assigned to photos in Project 02 (since there is no Ircat file) is there a way to add the Ircate file from Project 01 to Project 02?

(3) If yes, could you please provide step by step instructions.

(4) Other options.

Let me provide a little more detail. There is only one project out of several which didn't make the back up. Project 01 & 02 are the same. The only difference is that 01 was all of the work (edits) I completed in the field. Then when I returned to the office, I imported (01) and continued making edits. This is why I am referring to it as Project 02 = Project 01 + more edits.
