can i transfer saves through other versions?
you dont need to transfer the save data just redownload with the new update and play.
the save data now it's saving on locallow/hello crime folders from you pc (%appdata%) basically if you redownload with the new update and with no replacement you save data will continue on the new game, to restart game you need to delete save data from locallow,
my recommendations is: redownload it, extract the folder, and play without replacement, if you save data is here, replace the existent folder of the game if not try checking where you save data is located but it's normally now it is located on locallow for every version of game you have from 2.5.0 and above
