# Upgrade multiple agents in an instance

When performing selective upgrade of an agent in an instance, you can select multiple instances to upgrade at once.

## Before you begin

Supported Operating Systems: Windows, Linux and macOS.

Agent Client Collector installs need to access this URL: `https://install.service-now.com/`. MID connected agents can download the installer from the MID Server \(`https://<MID-WEBSERVER-URI:PORT>/static/acc_installers`\).

Select the version to which you want to upgrade your agent.

1.  Navigate to **All** &gt; **System Properties** &gt; **All Properties**.
2.  Select **New**.
3.  Assign the following values:
    -   Name = **sn\_agent.agent\_upgrade\_version**
    -   Type = **string**
    -   Value = The version number to be upgraded to, in the format &lt;major\_version.minor\_version.patch\_version&gt;. For example: **4.3.2**
4.  Select **Submit**.

If you do not select a version, the agent automatically upgrades to the current Agent Client Collector Framework scoped app version.

When working with MID-less agents, ensure that the agents can communicate with the ServiceNow Content Delivery Network \(CDN\). For details, see [Configure a download proxy for Agent Client Collector upgrades](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/agent-client-collector/configure-agent-upgrade-proxy.md).

Role required: agent\_client\_collector\_admin

## About this task

You can select up to 50 agents at a time for upgrade. To upgrade large numbers of agents, incorporate the Agent Client Collector into your software deployment tools.

Selective upgrade doesn't support Agent Client Collector to MID Server communication via mTLS.

## Procedure

1.  Navigate to **All** &gt; **Agent Client Collector** &gt; **Agents**.

2.  Select the check box next to the agents that you want to upgrade.

    You can select up to 20 agents.

3.  In the **Actions on selected rows...** box, select **Upgrade agent**.

4.  In the confirmation dialog box, select **Upgrade**.
