I would try to copy some of your original saves to a USB device (or the cloud), or potentially removing some games or software from the PlayStation 5 harddrive, and see if the merging works after that.It does find it (and as in the video I use an USB Storage Device), but I don't know why it won't allow me to merge the progress as it mention there isn't sufficient space and I need to delete some of the JWE2 saves.
