Upgrade Script

[valtam]

Looking to give people a way to upgrade, interactively and easily. The upgrade will ONLY be applicable for LL series releases ie. You will be able to upgrade from any version in the 2.0 - 2.8 series, but not from the 2.0 to a future 3.0 series.

This feature has been requested a lot. The script is in it's infancy, there is still much to do. If you'd like to test do the following:

1) Do a fresh install of 2.0 to a Virtualbox.
2) Make a file called lite-upgrade and make it executable.
2) Copy the script to /usr/bin
3) Click on the Whisker Menu and type in: gksudo lite-upgrade in the search box. Follow the prompts.

Of course I welcome code contributions and suggestions

This is what I have so far:
