In OOTP 23, click on "Settings," then the "Troubleshooting" tag. Then click on "Open folder containing saved games."

In OOTP 24, do the same.

Copy the game you'd like to import from the OOTP 23 saved games folder to the OOTP 24 saved games folder.

Now, when you try and import the game in OOTP 24, you should be able to see it in the OOTP 24 saved games folder. (You still have to import it for it to work in OOTP 24.)
