I am using Ubuntu 11.04 (Natty) as a wubi installation in my laptop. i.e inside windows, in A drive. Now I need to move to another laptop. I found instructions for the backing up in https://help.ubuntu.com/community/BackupYourSystem
Now as a rule, I would be getting a new laptop with Windows again I need to use wubi. So in my new system I want to try 11.10 instead of 11.04
If I create a backup of 11.04 and in my new laptop if I upgrade to 11.10, can I restore it back in 11.10?
