RE: [Linux-cluster] RHEL 4.5 -> 4.6 migration

I have done similar, but again, all nodes at once (due to the fact that they all had all the filesystems including root shared via GFS). My upgrade was 5.0->5.1, though.

We have migrated from 4.5 to 4.6 without any problems, however all nodes
at once - would not recommend different versions on nodes within the
same cluster.

Others might have other ideas?

	Has anyone migrated from an existing 4.5 to the newer 4.6
cluster suite?  We would like to roll out 4.6 in our 11-node cluster,
but only one node at a time, over the course of 2-weeks.  Does the two
versions intermix well enough to do that?   Or do we need to do take
some kind of special care or precaution, like when injecting this
dilithium crystal chamber with an inverse tachyon pulse from the main
deflector dish?
