I used to run Ubuntu Netbook Edition (UNE) 10.04 on my Asus Eee 901.
I recently upgraded to the "regular" Ubuntu desktop 11.10, since UNE was discontinued.
Due to the limited hardware, my netbook has become slow, which is why I want to switch to Lubuntu.
Can this switch be done easily in connection with a normal upgrade process? Ie can I install a package or edit a software sources-file somewhere, that will alter my upgrade path to Lubuntu, so that I don't have to do a complete reinstallation?
