# Upgrade the Agent Client Collector manually on a Windows system

Perform a manual upgrade of your existing Agent Client Collector version on a system running a Windows OS.

## Before you begin

Backup the Agent Client Collector configuration files, such as `acc.yml`, `check-allow-list.json` and `agent_now_id`. The `agent_now_id` is located in the cache directory: `C:\ProgramData\Servicenow\agent-client-collector\cache`

Backing up configuration files is a safety precaution to safeguard the files during the upgrade. Configuration files need to be restored only if there are upgrade issues which require new installation.

\(Optional\): Enable golden image mode for cloning additional agents by setting the msi property **GOLDEN\_IMAGE=true**.

Role required: agent\_client\_collector\_admin

## Procedure

1.  Upgrade to the new agent version, as described in [Upgrade an agent in an instance](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/agent-client-collector/upgrade-agent-from-instance.md).

    You can use either the manual or single-line procedure. When restoring backup files, the system replaces the configuration file values.

2.  After installation is complete, you can delete the backup files.
