You can always download the worksheets into files and save them to some 
reasonable place. (With an open worksheet such an option is in File menu, I 
think).
Normally it's a file with .sws extension.
And you can do the opposite, load a worksheet from a file.

I'd recommend to install a new version of Sage, not to upgrade the existing 
one (an upgrade from such an old version won't be possible anyway).
Then you can load your worksheets into the new version.
