LVM 1.0.3 supports both version 1 and 2 of the metadata.
There is "*no* need to run any metadata update tools".
Full announcement here.
from the announcement to lkml:
Changes to LVM 1.0.2 include:
o vgcfgrestore supports restores to different sized physical volumes;
useful in cases where a replacement disk is a little bit to large or
for test purposes; option enhancements; physical volume UUID restore fix
o vgchange removes failed snapshots and activates the volume group rather
than failing on it. Optionally forces device number changes in cases
where it finds clashes so that the volume group can be activated
o vgexport exports volume groups not showing up in /etc/lvmtab*
o vgscan can drop all snapshots or those in a particular volume group now
o "pvmove -i" ignores read errors while moving and supports moves in
inactive volume groups
o > 1 TB fixes for physical and logical volumes (2 TB limitation
on 2.4 persists)
