Start AECOsim model with wrong Dataset

Question

Hello, 
 
 My team start a model with a wrong dataset (Dataset_NE) at the beginning. And now I wish to correct it to right dataset (Dataset_US) setting. Is there a recommended process of doing so while save as much as work we had done so far? 
 Thanks,
