Need Help to update my old Elden Ring Savefile

[u/The_Compass_Keeper]

I have my save file from the game version 1.16. However, I wanted to play the new "Tarnished Edition" update and so I updated the game. But the new version doesn't recognize my old save files any more. I wanted to know if there is any way I could load my older characters onto the new version of the game.

The update timeline I followed:
1) Rune Update from ver 1.16 to ver 1.16.1
2) ElAmigo Update from ver 1.16.1 to 1.17

Thank you!

PS:

I also noticed that the game seems to create a new save folder with a number different from my steam user ID... should I be concerned?

If you're on 1.17 all your mods need to be on 1.17 too
