<p class="MsoNormal">I’m testing the Train7->Ussuri8 upgrade on a heat stack, following this document:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><a href="https://docs.openstack.org/kolla-ansible/train/user/centos8.html#migrating-from-centos-7-to-centos-8">OpenStack Docs: CentOS 8</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I used the instructions here to successfully remove a controller from the cluster:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><a href="https://docs.openstack.org/kolla-ansible/train/user/adding-and-removing-hosts.html#removing-existing-controllers">https://docs.openstack.org/kolla-ansible/train/user/adding-and-removing-hosts.html#removing-existing-controllers</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now I’m ready to add one, using the instructions here:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><a href="https://docs.openstack.org/kolla-ansible/train/user/adding-and-removing-hosts.html#adding-new-controllers">https://docs.openstack.org/kolla-ansible/train/user/adding-and-removing-hosts.html#adding-new-controllers</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">They say to run bootstrap-servers:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">kolla-ansible -i <inventory> bootstrap-servers [ --limit <limit> ]<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The question is, how to run it? My build server is running Centos 7 and has Python 2.7.5. Should I just download Ussuri to my existing build server, or do I need to build a new Centos 8 build server with Python 3?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I read the “<span class="std"><u><span style="font-size:10.5pt;font-family:"Segoe UI",sans-serif;background:white"><a href="https://docs.openstack.org/kolla-ansible/train/reference/deployment-and-bootstrapping/bootstrap-servers.html#rebootstrapping">potential
issues</a></span></u></span><span class="std"><span style="font-size:10.5pt;font-family:"Segoe UI",sans-serif;background:white">” text but it’s not obvious whether it is safe to run Ussuri bootstrap-servers on Train hosts. If I don’t run bootstrap-servers
on the Train controllers, then how does the new Ussuri controller get integrated (RMQ, MariaDB, etc.)?<o:p></o:p></span></span></p>
<p class="MsoNormal"><span class="std"><span style="font-size:10.5pt;font-family:"Segoe UI",sans-serif;background:white"><o:p> </o:p></span></span></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I apologize for the nonsense below. I have not been able to stop it from being attached to my external emails.<o:p></o:p></p>
