Thanks for the hint! Tying it I get some message like these:
DEBUG: node!=node: number of children differ

In Detail it seems the new software wants to see <instance_attributes> inside
<node>, and does not want to see:
      <nvpair id="h04-utilization-attributes" name="attributes"></nvpair>
      <nvpair id="h04-utilization-standby" name="standby"
value="off"></nvpair>

So is it too much to expect for an upgrade to fix the XML syntax it it
changed?
(The output of "cibadmin -Q" does not indicate the XML schema being used)

It's not "filing an issue"; it's "make people aware" before they run into the
same problems that I did.
