Since the newest DLC seems to be a Steam exclusive, at least temporary, I wondered, whether I could migrate to that platform until Red Hook graces GOG with an update. However, I'd prefer not to start from scratch.

Has anyone tried to export the savegames from GOG Darkest Dungeon to the Steam one aand vice versa? How would one do it?

I bit the bullet and bought the game on Steam. In case anyone wonders, the saves transfer automatically with no actions required on behalf of the player.
