In case you just want to update your LVM software, you don't need to
vgexport/vgimport your VGs as described under that URL.

Presuming that you took backups of your data and metadata (/etc/lvmconf/*)
and don't have root on a LV, you just need to install the new LVM software
(take LVM 1.0.3!), and run "vgscan;vgchange -ay" after the successfull
installation and reboot. "vgscan;vgchange -ay" is probably in your system
startup script anyway.

To be save, you could copy your LVM 0.8 software to /sbin/lvm-0.8 (tools) and
/lib/lvm-0.8 (library) respectively. Make your LVM 0.8 capable kernel
bootable too.

With these preperations, you still can boot into single user for LVM 0.8
recovery in case something goes wrong.
