+## Limitations
+
+- Do not pause platform upgrades for clusters if _all_ of the following conditions apply:
+
+  - Your cluster is an Edge cluster.
+  - Your Palette/VerteX instance is on version 4.5.x or later.
+  - Your agent version is older than 4.5.0.
+  - Your Edge cluster has the
+    [local Harbor registry](../../edge/site-deployment/deploy-custom-registries/local-registry.md) enabled.
+
+  Using an agent version older than 4.5.0 with Palette/VerteX versions 4.5.x or later may lead to image download issues,
+  issues with pushing images to the local registry, and cluster deployment issues. Ensure that you enable platform
+  upgrades so your agent can be upgraded to be compatible with Palette/VerteX.
+
 ## Prerequisites
 
 - Cluster admin permissions or Tenant admin permissions when pausing upgrades for all clusters within tenant scope.
