Is it not possible to move an existing vault cache to a new location?

Are you sure about that? I’ve read information suggesting it is not possible for the Epic Games Launcher to use an existing vault cache folder. This is exactly why I do not want to try this until I’m sure. I could switch it to a different location, nothing gets moved, and then when I switch it back, the Epic Games Launcher will act like the existing data isn’t there and re-download all the content I wish to add from my vault. I have been told this by multiple people.
