is it possible to upgrade from ubuntu 8.10 desktop to 9.04 netbook remix?

There's a lot of different ways you can do this. Midnight's answer looks like a good way of keeping not just your settings & data intact but also keeping any installed programs :)

@ Tom

Thank you for the flowers Tom.
I tend to not destroy/reset any data if possible.

btw: It's hard to answer anything here before you do. Do you ever sleep? ;-)

Lol, thanks, i tend to be here a lot for a while and then vanish for a week or two and then reappear. I think there's a large area of overlap between your areas of expertise and my prefered areas. Actually there's 3 of us ;)

thanks. i have upgraded it only to 9.04 desktop though not netbook remix.

Thanks midnightflash, that solved my question.

Great! Now you can do the following to get it to UNR:
Open Synaptic (System -> Sytem-Settings -> Synaptic-Packaging) and search for "ubuntu-netbook".
There you will find the packages (that will also install all the dependencies) to get the system over to UNR.

Greetings!
