Upgrade Steps

This section describes how to upgrade Coveo for Sitecore from December 11, 2020 (5.0.858.1) to February 12, 2021 (5.0.900.5). If you're upgrading over multiple versions, Coveo has a procedure to streamline the process.

Important For the best Coveo for Sitecore experience, always follow the Leading Practices When Upgrading Coveo for Sitecore.

Step 1: Upgrade Coveo for Sitecore

Important Make sure the Microsoft MVC security update MS14-059 is installed on every Sitecore host in your environment..
  1. Log into the Sitecore Desktop.
  2. Access the Installation Wizard (Sitecore Start Menu > Development Tools > Installation Wizard).
  3. Upload and install the Coveo for Sitecore 5.0.900.5 package built for the specific version of Sitecore you’re running (for example, Sitecore 9.0). You can find it in Downloads.
  4. When prompted to overwrite files, click Yes to all.
  5. When prompted to overwrite items, select Overwrite, then click Apply to all.

    You might be prompted twice with this question. Select the Overwrite option and click Apply to all both times.
  6. Once the installation is completed, make sure that you restart both the Sitecore client and server.

Step 2: Manually Update the Coveo Configuration Files

The Coveo configuration files are located in the App_Config\Include\Coveo folder. When upgrading, you must compare the changes to the .example files from your current Coveo for Sitecore version with the ones in the build you’re upgrading to. Then, you can merge these changes into your current configuration files. This method lets you keep your customization intact, while still benefiting from the latest enhancements brought in the product. You can use a merge tool such as WinMerge to accomplish this.

In further detail, here are the modifications that you must perform to the configuration files resulting from the feature changes between the previous and current Coveo for Sitecore releases:


Sitecore 8.1

The closing </coveo> tag location has changed. It’s now located immediately before the opening <contentSearch> tag, as shown below.


Apply these changes in your configuration.

⚠️Step 3: (Optional) Leverage the new CleanHtmlWithSimpleSelectors processor


The CleanHtmlWithSimpleSelectors processor had to be deprecated in the March 26, 2021 release of Coveo for Sitecore. Don’t perform the steps below which would activate the CleanHtmlWithSimpleSelectors processor.

Instead, should you want to remove HTML sections from Sitecore items using CSS selectors, refer to our new article on indexing pipeline extensions (IPEs) which contains a Python script sample you can easily adjust for your specific needs (see Remove HTML Sections From Indexed Sitecore Items).

The CleanHtml processor configuration will be kept if existing. However, we strongly recommend to move to the new CleanHtmlWithSimpleSelectors, which offers an easier way to clean HTML content by using simple CSS selectors.

You can move to the new processor by changing your indexing options in the Command Center. Disable and enable again the Index rendered HTML option. The new processor will then be activated.

The new processor comes with the default selector .coveo-no-index. It’s also possible to customize the list of selectors that the processor uses to clean HTML content.

Step 4: (Optional) Leverage the New Category Facet Data Source Options

This version of Coveo for Sitecore adds support for the recently added displaySearchOnTop and displaySearchButton Coveo JavaScript Search Framework component options. For more details on these options and how to leverage them, see Coveo Category Facet - Data Source Options.

Step 5: Publish Your Site

In the Sitecore Content Editor, perform a publish site action. This ensures any changes related to Coveo components in the upgrade are published to the web database.
