Is it possible doing something like that 
?
Well you would just have to load the players data from dss2 and then save it through the normal system. The most complicate part about doing this is just checking whether the data is already converted or not before loading so players dont lose data.
it shouldn’t be too big of a problem I could just look if the player has no data in the new datastore then it will save else it will be ignored, but thank you for the idea it helps a lot.
