Changing the CES Service Port

You may encounter a situation where you need to change the CES service port for a Coveo server. Select an appropriate port number (see About the CES Service Port).

Example: When you plan to upgrade the Coveo Platform from one major version to another, like from version 6.x to 7.x, you can install the two instances on the same Master server, but you need to ensure that the two instances use different CES service port numbers, like 52800 for version 6.x and 52801 for version 7.x.

You need to change the CES service port on the Master server and on each Front-End Server or your Coveo instance.

To change the CES service port on the Master server

  1. Using an administrator account, connect to the Coveo Master server.

  2. Open the Administration Tool (see Opening the Administration Tool).

  3. In the Administration Tool, select Configuration > Advanced.

  4. In the Advanced page, change the Port value and then click Apply Changes.

To change the CES service port on a Front-End server

  1. Using an administrator account, connect to the Coveo Front-End server.

  2. Using a text editor:

    1. Open the [.Net_Front-End_Path]\Web\Web.config file.

    2. In the <coveoEnterpriseSearch> section of the file, change the port value in the following line:

      <server hostname="localhost" port="52801" sslCertificatePath="D:\CES7\Config\Certificates\cert-iis.p12"/>  
    3. Save the file.
