<p><font size="3" face="serif">I remembered I saw somewhere about how to upgrade, (step by step in updating from J to K or others)<br>
I think it's best and suitable way to use this kind of 'different version' talking to make compute host alive<br>
during system upgrade.</font>
<p><font size="3" face="serif">so I believe controller should be upgrade first the compute node to be update set by set<br>
that means Kilo conductor should works with Juno compute<br>
but on the contrary I didn't see a value for supporting it....</font><br>

No, that's not valid behaviour. You need to upgrade the controller <br>
infrastructure (conductor, API nodes, etc) before any compute nodes.<br>
