I am currently running Ubuntu 12.04 and would like to upgrade/update it to 13.10 without losing my files. I have the Ubuntu One cloud but I have limited space. Is there any way to get a different version of Ubuntu without having to lose my files or upload them to a cloud?

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.

IMO, your best option is to do fresh install of 13.10 , your data in /home will be preserved. NOTE: 13.10 is at EOL in July. – bodhi.zazen Feb 19 '14 at 17:05

I am not 100% sure, and you should back up your data. but back up is must if you are installing from USB or cd/dvd.

directly upgrading from servers is much more safer, and most probably will not lose data, i am not sure about added applications. as you can see it Upgrade is mentioned as recommended. (and not dvd/usb) when you upgrade 11.04 to 11.10make sure that your 11.04 is completely is recommended only when you have a complete successive version installed, which applies to your case. so not an issue.keep that in mind.sometimes applying old data to upgraded version can cause errors.To cut a long story short.(you can download 11.10 ISO to usb/dvd,

for other uses in future, but dont install from them)

go for a network upgrade

(instructions given here, ithink will be the same for 11.04to 11.10)

take back up for safety, but upgrade from network and not usb/cd/dvd.
