The situation, and it's history:

R1.) /project/path contains a lot of the files and directories, with logs

R2.) /project/path was deleted a year ago.

R3.) Replaced via add, with local copy of /project/path. (40% of files are unchanged, else deleted)

R4.) Year after, /project/path has a lot of changes, with logs

---

Now we want to restore R1 + R4 logs history for those files in /project/path.

Is any possible ways to do this ? Unfortunately I have not found the way to do this.

---

UPDATE:

The end result should be R4 file set, but with R1 + R4 logs.
Currently we need to review logs in both R1, R4.
