Clean up grade FC6 to F7 while keeping data in LVM partition

[coldspring]

When I installed FC6 I created 4 partitions on my hard drives on the advice of the MythTV installation Howto.

I now have the following partitions:
A swap space,
a boot partition,
a partition for FC6 (about 2G)
and an LVM partition for data (325 G) that spans two physical drives.

The reasoning behind this configuration was that when the time came, I could do a clean upgrade from FC6 to F7 by completly removing FC6 and replacing it with F7 without wiping out my data.

So here is my question: Given that I have a set of F7 Disks: Exactly how do I do the upgrade so that I completely wipe out FC6 then replace it with F7 without wiping out the data on the LVM partition and do it in such a manner the the new F7 system can access the data on the LVM?

It's easy.

You do an install from the dvd (not the livecd).
Proceed as normal to the disk drives to use in this install and make sure they are all checked.
Select custom partitioning scheme.

for /boot select sda1 partition and say edit. (select /boot as mount, ext3 as type, and check/select format
for swap - edit, type swap, no mnt point, format optional.
for / (root) same as #1 above.
for lvm (schroll up)- edit the vg, select the lv for /home at the bottom box, then click edit over to the right, select mnt as /home (no format)
for next lv (if any) same thing, just select the mnt point.

Then check the disk druid screen to make sure the the /mountpoints show correctly, and only the ext3 /boot, /root are to be formated.

proceed as usual.
Use the same hostname, users and passwords for best results.
