Thanks a lot for the info Steve - That'll certainly help when actually
decommisioning the CE! However, I'm still unsure about how to switch the
availability/reliability tests to Dirac/VAC. I'm assuming this is
possible but I don't know who runs them, whether the switch is possible,
if it's still based on Nagios tests, etc. Does anyone have any info
about that?
Thanks!
Mark
