Description

When upgrading UCP, you must run the upgrade command against every Engine in your cluster. You should upgrade your controller and replica nodes first, followed by your compute nodes. If you plan to upgrade your Engine as well, upgrade the Engine first, before upgrading UCP on the node.

After upgrading each node, confirm the node is present in the UCP console before proceeding to the next node.
