[Pacemaker] Howto upgrade Pacemaker cluster from Version: 1.0.2 to the last released on clusterlabs

[Roberto Giordani]

Hello,
I'd like to know how is it possible to upgrade a running cluster
pacemaker on Opensuse 11.2 version 1.02 to the last available on clusterlabs
using dlm + ocfs2 too

Could someone explain in some steps how to proceed without loose all the
cluster configuration up and running?

Regards,
Roberto.
