Upgrading on a LVM based system

Hi all, Since Fedora 7 Test 4 is finally out, I am about upgrading my FC6 and thus help with testing F7. The problem is I created one logical group with three logical volumes in it: /, /boot and /home and I'd like to keep this layout and the /home volume. Is there any way how can I do clean install of F7 into this layout without having to erase the /home partition? Thanks for your suggestions, Martin
