Last month, Microsoft launched a new feature: associate a hub site to another hub site.

This functionality will add the ability to associate a SharePoint hub site to another hub site to expand search results across multiple hubs in your organization. This will enable users to discover relevant content when searching on any sites related to the associated hubs. In this post, we will look at how to associate a hub site to another hub site.

When this will happen:

This feature is currently in preview and may not be available in your tenant.

Targeted Release Customers – End of September 2021

All Customers – End of October 2021

What changes you will see:

When you associate hubs, there are no visual changes to the user experience except for when users search for content. Below please find a table for better comparison between Associated child hub site and Associated child site.

How to associate a hub to another hub:

You can run a PowerShell command to associate a hub site with a Parent hub site.

(Note: This feature is currently in preview and may not be available in your tenant.)

Before running a PowerShell command, you will need to know HubSiteId for both Parent hub site and Associated child hub site

  • Run this command to get the HubSiteId for Associated child hub site:
            Get-SPOHubSite -Identity 

               Bp1

  • Run this command to get the HubSiteId for Parent hub site:
            Get-SPOHubSite -Identity 

               Bp2

  • Run this command to establish hub to hub association
Add-SPOHubToHubAssociation -Source  -Target 

      Bp3

Please see Microsoft Documentation to learn more about this PowerShell command.

Please see Microsoft Documentation which explains this functionality in more detail and also shows how to achieve this from SharePoint Admin Center.
