Yes you can upgrade from CD using the following procedure

Use this method if the system being upgraded is not connected to the Internet.

1. Download the alternate installation CD
2. Burn the ISO to a CD and insert it into the CD-ROM drive of the computer to be upgraded.

*If the ISO file is on the computer to be upgraded, you could avoid wasting a CD by mounting the ISO as a drive with a command like:

sudo mount -o loop ~/Desktop/ubuntu-9.04-alternate-i386.iso /media/cdrom0

3. A dialog will be displayed offering you the opportunity to upgrade using that CD.
4. Follow the on-screen instructions.

If the upgrade dialog is not displayed for any reason, you may also run the following command using Alt+F2:

gksu “sh /cdrom/cdromupgrade”

Traduzindo para português, é só inserir o cd com o ubuntu 9.04 na drive (ou montar o iso) e seguir as instruções

EDIT: Se tudo correr bem, não há perda de dados ou configurações. Em todo o caso recomendo uma instalação limpa
