* ![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read

Convert MID-based Agent Client Collector (ACC) to MID-less ACC by adjusting the configuration in acc.yml, decoupling from a specific MID to enhance flexibility and adaptability.

## Before you begin

Verify that the ACC registration key was set up and the ACC was installed. For more information, see the following:

* [Create an ACC registration key](https://www.servicenow.com/docs/daTdrcC1k0RcmSpwnJQs~w "Set up an Agent Client Collector (ACC) by creating an agent registration key to identify and authenticate agents that are enabled to send data to the collector. The key helps promote the security and integrity of the data collected from the system.").
* [Install ACC for DEX on Windows](https://www.servicenow.com/docs/XFmgyhMjdWyqiqt0MZRweA "Install Agent Client Collector (ACC) to work with Digital End-User Experience (DEX) to monitor and collect data, provide insights into system performance, identify issues, and enable proactive maintenance.") or [Install ACC for DEX on macOS](https://www.servicenow.com/docs/tqYzXi8_OnMytkXKnTJKng "Install Agent Client Collector (ACC) to monitor and collect data in a centralized and organized manner, provide insights into system performance, identify issues, and enable proactive maintenance.").

Role required: agent_admin and agent_client_collector_admin

For more information, see [Agent Client Collector user roles](https://www.servicenow.com/docs/access?context=acc-users&version=australia&pubname=australia-it-operations-management&ft:locale=en-US).

## Procedure

1. Stop ACC based on your operating system:
   * For Windows, access Services as administrator and stop the Agent Client Collector Service.
   * For macOS, execute the command: `sudo launchctl unload -w /Library/LaunchDaemons/com.sn.acc.plist;`.
   {#convert-midbased-acc__choices_hxr_sw3_hcc}
2. Open the acc.yml file.
3. Edit the instance URL.
4. Edit the backend-url parameter to point to \<ITOM Cloud Services Gateway\>.  
   Use one of the following gateways based on the instance location:
   * AMER: itomcnc-prod-gateway-amer.sncapps.service-now.com:443
   * EMEA: itomcnc-prod-gateway-emea.sncapps.service-now.com:443
   * APAC: itomcnc-prod-gateway-apac.sncapps.service-now.com:443
   {#convert-midbased-acc__ul_alf_cph_hxb}

   For more information on how the Agent uses the ITOM Cloud Services Gateway, see [DEX Architecture](https://www.servicenow.com/docs/W~_XWZu9hWRobshdEW~VDg "Digital End-User Experience (DEX) architecture describes the cloud-native services, endpoint agents, and data flows that connect end-user devices to your ServiceNow instance.").
5. Configure the following parameters:  
   * connect-without-mid: true
   * instance-url: \<full_instance_url\>For example: https://dex.servicenow.com.

   * insecure-skip-tls-verify: false
   * registration-key: \<registration key value\>For more information, see [Create an ACC registration key](https://www.servicenow.com/docs/daTdrcC1k0RcmSpwnJQs~w "Set up an Agent Client Collector (ACC) by creating an agent registration key to identify and authenticate agents that are enabled to send data to the collector. The key helps promote the security and integrity of the data collected from the system.").

   {#convert-midbased-acc__ul_dlh_f3q_2xb}
6. Comment out the API key parameter:  
   `api-key: "encrypted...."`
7. Save the file.
8. Delete files based on your operating system:
   * On Windows, navigate to /agent-client-collector/config/cert/cnc and remove the following files: cnc_chain.crt and priv_key.pem.go.
   * On macOS, access /Library/Application Support/servicenow/agent-client-collector/cert/cnc and delete the files: cnc_chain.crt and priv_key.pem.
   {#convert-midbased-acc__choices_avn_pw3_hcc}
9. Delete assets.db, queue.db, and all subdirectories in the cache folder based on your operating system:
   * On Windows: /agent-client-collector/cache.
   * On macOS:
     * For Agent 3.4.1 or above: /Library/Application Support/servicenow/agent-client-collector/cache.
     * For Agent 3.4.0 or below: /Library/Caches/servicenow/agent-client-collector.

   {#convert-midbased-acc__choices_yhb_vw3_hcc}  
   Important:  
   Keep agent_now_id in the cache folder.
10. Initiate the ACC service based on your operating system.
    * On Windows, open Services as administrator, then start the Agent Client Collector Service.
    * On macOS, use the command: `sudo launchctl load -w /Library/LaunchDaemons/com.sn.acc.plist`.
