I don't see any reason why just copying the data folder to a backup or pocket drive wouldn't be OK. When you reinstall the app it will make a new data folder but just put your good one (from backup) on your new big disk/ssd and point the app to it. After you see it's working OK you can then delete the new user folder the app made on re-install. Hope that makes sense. I have moved and renamed data folders quite often. Just make sure app points to correct folder. I rename data folders to something "non-cryptic" like "trainz data" and in my case I have a second install with a data folder of "trainz data beta"
