migrate to 1.2 from 1.1

[Gaspar Bakos <gbakos@xxxxxxxxxxxxxxx>]

Dear all,

I am migrating from kernel 2.4.18 + xfs-1.1-2.4.18 patch to
2.4.20 kernel and the relevant xfs-1.2-2.4.20 patch.

All partitions on my (RH7.3) computer are XFS v1.1 (including sw RAID-1,
the root partition, etc).

Question is: what shall I do? Will the newly patched 2.4.20 kernel mount
the older xfs partitions without making any damage? How can they be
migrated to xfs 1.2? Do I have to upgrade the xfstools before the reboot?
Will LILO and the MBR will be affected by the new filesystem?

Cheers
Gaspar
