Memory cards & Savestates after upgrading

[AlphaKennyTime]

When I download a new version of ppsspp I always take the memstick folder from the older version and drop it in the new one. Then I delete the old ppsspp folder and place the new one where the old one used to be. I've never had any issues. Do you move the new ppsspp to where the old one used to be? I didn't do that once and I got some error when I tried to start up a game but it worked again after I moved the folder.
