Upgrade vs Full?

[XnForFanKN]

When upgrading from Xenforo 1 to Xenforo 2, is it better to download the full package or the upgrade package? I know you typically download the upgrade package for an upgrade and the full package for a new installation. But I wasn't sure about going from Xenforo 1 to Xenforo 2 since it is such a major upgrade. What is the exact difference between the two packages?

Thank you.
