I have updated a box vagrant box update and now when I run vagrant up it boots into the old box. How can I update my box to use the newer version?

From the Vagrant docs:
Finally, you can update boxes with
vagrant box update. This will download and install the new box. This will not magically update running Vagrant environments. If a Vagrant environment is already running, you'll have to destroy and recreate it to acquire the new updates in the box. The update command just downloads these updates locally.
