upgrade with aptitude ?

[Pierre Meurisse]

Hi !

I'm managing 12 machines in a school, with ubuntu 10.10. I have to upgrade to
11.04.

I would like to know if I can do that with aptitude from my home (I have
ssh-access to every machine).  I would replace every occurence of
'maverick' with 'natty' in /etc/apt/sources.list, and then run aptitude.

Does it work if I do that ?

Regards.
