When I upgrade R, y make the second option, because
sometimes there are new bugs on the new version, or
some of my old functions don't work on the new version
for one reason or another...either way I install the new version
on a different place (usually the setup installs it on a new directory
rw1041) so there are independent.

And later if you want to delete the old version it is very easy...
Just delete the directory and the links and/or the shortcuts to
the Rgui.exe program. R is a very clean program (no register stuff... )

And yes... you must reinstall the packages, but I make
a copy of the \library directory to the new one... and then
I use the upgrade.package() function to get the latest
pre compiled packages.

Hope this will help.
