# Upgrading the ICAgent

To ensure better collection experience, AOM will continuously upgrade ICAgent versions. When the system displays a message indicating that a new ICAgent version is available, perform the following operations:

1. Log in to the management console.
2. Under Application, click Application Operations Management.
3. In the navigation pane, choose Agent Management.
4. Upgrade the ICAgent. ICAgents are upgraded in batches by cluster. That is, ICAgents on all hosts in a cluster are upgraded at a time. For hosts where ICAgents have already been uninstalled, ICAgents are installed on them again.

   1. Select Cluster: xxx (xxx indicates the name of the cluster created on the CCE console) from the drop-down list on the right of the page.
   2. Click Upgrade ICAgent. In the displayed dialog box, click Yes.

   The ICAgent begins to be upgraded. Please wait. When the ICAgent status changes from Upgrading to Running, the ICAgent is successfully upgraded.
