This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

You can't. You need to do a full install. – user25656 Jul 13 '13 at 11:47
can I install 13.04 from iso folder extracted to my Ubuntu desktop ? – Anis Jul 13 '13 at 11:50

as i know you could not skip versions (incompatibility issues), and you must do it step by step

i recommend you to:

update your version to latest using cmd

sudo aptitude update && aptitude upgrade

and then

sudo do-release-upgrade -d

and you will upgrade to next version....after that you will do the same, and you will go to the next version

good luck

leon, it's not working. Apperently It's not possible even to make upgrade version by version. I will make fresh installation. Thanks – Anis Jul 13 '13 at 12:34
From what I understand, Ubuntu generally uses apt-get. Is there a specific reason you recommend aptitude over apt-get? Do you know if OP has aptitude installed? Wouldn't OP have to install aptitude first? Shouldn't that be part of your answer? What advantage does going from 11.04 to 11.10 to 12.04 to 12.10 to 13.04 confer over doing a clean install of 13.04 over the existing 11.04 (after backing up essential user data)? – user25656 Jul 13 '13 at 12:43
