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.

I say this every time: always keep two backups of your data before doing anything system-wide. – don.joey Jun 27 '13 at 16:48
I think you can't upgrade directly from 12.04 to 13.04. First upgrade to 12.10 then 13.04 but before that back up your data's – Ashok Jun 27 '13 at 16:59

In the update manager there will be an option to upgrade to the next verion of Ubuntu. You might have to go via 12.10 if you are unlucky.

I generally found though that upgrading would introduce subtle but irritating bugs into the system. So I would recommend just backing up your home folder (an any others containing data you want to keep), making a note of programs/applications you have installed, and performing a clean install.

It is not that much more effort (takes 20-40 mins) and is likely to provide a smoother running system.

Good Luck!

Yes you can, but first you will have to upgrade to 12.10

Recently I have upgraded my OS from 12.04 to 12.10 & then after 12.10 to 13.04.

But it's always recommended to keep backup of your data before going for any version upgrade, so better keep it.
