[rhn-users] RHEL3 => RHEL 5 - failover/clustering?

[Mertens, Bram]

Depending on the applications you intend to run on these machines upgrading to RHEL 4 might be a better option still.  AFAIK not all middleware and such is certified for RHEL 5 yet so you might want to check that first.

Regards

Bram
