I am using Ubuntu 12.04. I wish to upgrade it to 14.04.
My current partitions are -
I want to upgrade without wiping out my data. What should be the appropriate partitions ? I have a 14.04 iso image with me.
EDIT - I am not getting the option to upgrade while booting via USB. Other two options are to install in along side or erasing and installing a fresh 14.04. Is it anything I can do to upgrade , without erasing? If no, please suggest me some partition examples so that I can partition my space right now and then erase only the required space.
