Android save games can't be found after updating to UE5

Development Platform & Builds
1

I am releasing an Android app.

I have currently uploaded an app I made with UE4.27 to the store, but I need to update to UE5.2 due to Google requirements.

I can update it with the build I made with UE5.2 without any problems, but I can’t find the save game.

If I update again with the UE4.27 version, the save data is found. So I don’t think the save game itself has disappeared, but I can’t load it, and the node that checks if there is a save game says there isn’t one.

I try not to change the package name of the app at all.

Maybe the save directory has changed?

When I view the project save directory, it doesn’t look like it has changed.

Can I use UE4.27 save data in UE5.2?

@saito_y Did you find the solution?

I think I have found an Insight!

I found that ue4 save games were saved in the path.

/data/data/[PackageName]/files/UE4Game/[ProjectName]/[ProjectName]/Saved/SaveGames/SaveGame.sav

and ue5

/data/data/[PackageName]/files/UnrealGame/[ProjectName]/[ProjectName]/Saved/SaveGames/SaveGame.sav

It switched from UE4Game to UnrealGame!! And that’s why it did not find the save game!
So now I think it would work if we copy ue4’s SaveGame to the new directory!

Note that in my case I have turned on UseExternalFilesDir for UE4Games/UnrealGames
and for that, it was in /data/data…
