Upgrading to 10.04 LTS amd 64

[esky64]

Hi All
I'm using Ubuntu 9.10 and have a few problems eg can start update manager, Software centre software sources. So I wish to upgrade to 10.04LTS AMD 64.
I have set my system to dual boot ubuntu/windows with a large partition where my Home folder is placed Ubuntu/Windows both use same partition. I have never done a upgrade with system like this so Question is how do I make sure that the upgrade leaves system the same I wish to not format Ubuntu/windows partition and leave it as my home folder.
Hope what I have written makes sense
Thanks
