Description
It would be nice to have a page somewhere that documents more specifically what the choices posed by the installer mean.
I am unsure about the difference between the "Full" vs. "Upgrade" within these choices, or if there is any difference between "upgrade / install" vs. just "upgrade".
Unless there are some rules or restrictions about specific versions I think I'd lean towards dropping the term "upgrade" altogether, to me "upgrade" implies that the process is potentially one way (i.e. increase version only), or perhaps could have rules like "only allowed to go by 1 major or minor version at a time" but as far as I know there are no restrictions on the versions, this tool could be used to go up or down to any version theoretically I think, so maybe just "Install" is a little more clear.
