リンクのコピーリンクがクリップボードにコピーされました!
The overcloud upgrade process disables the main control plane services at key points. You cannot use any overcloud services to create new resources when these key points are reached.
It is important to plan a maintenance window to ensure that no users can access the overcloud services during the upgrade.
For information about the duration and impact of this upgrade procedure, see Upgrade duration and impact.
