-  If your upgrade is successful, repeat steps 1 to 4 on the next host in your
-  high availability |onprem| deployment.
+  |onprem| remains in **Upgrade Mode** until every host is upgraded. For 
+  :doc:`high availability configurations </tutorial/configure-application-high-availability>`, 
+  this means:
+
+  - Your hosts might not be fully operational until the upgrade is completed     
+    cluster-wide. If your first host upgrade takes longer than expected, continue 
+    upgrading the other hosts.
+
+  - Do not stop or cancel processes that seem stuck as this might disrupt the upgrade.
+
+  - The logs that |onprem| generates during startup might temporarily pause 
+    at ``Starting pre-flight checks`` while |onprem| upgrades all its servers
+    to the same version. 
+ 
+  - For multi-version upgrades, do not skip major versions.
+    You must upgrade each node in the cluster to the last minor version of each major release one at a time.
+    For example, to upgrade from 6.0.26 to 8.0.3, do the following steps on *each node*:
+
+    1. Stop the service on a node (running 6.0.26).
+    2. Upgrade to the most recent minor version of 7.0.x.
+    3. Start the upgraded host before you move to the next node.
+    4. Repeat for all other nodes.
+    5. Repeat this process to upgrade each node from 7.0.x to 8.0.3.
