Update Sage-4.8 VirtualBox server to 5.0

[TSchwenn]

How should I update my Sage VirtualBox (sage-4.8.ova) server to 5.0? I don't want to start from scratch with a new install (i.e. with sage-5.0.ova). There is no mention of updating at http://wiki.sagemath.org/SageAppliance

Theoretically you should be able to run `sage --upgrade` in a terminal on the virtual machine. Can you try that?

That worked, after several hours of compiling.  The notebook server reports version 5.0 and runs worksheets fine, but the help/documentation links are all broken ("Document does not exist.")  How can I restore the documentation?

Go to the root directory of the Sage installation and type `./sage
--docbuild all html`. This will unfortunately take some time, because
the documentation builder is pure Python and doesn't do any
parallelization.

About an hour later: "build succeeded, 2 warnings."  The documentation is all there now.  Thank you!

Sure. Actually I wonder why `sage --upgrade` doesn't automatically
rebuild the documentation...
