The hybrid taxonomy feature allows you to extend your on-premises taxonomy into SharePoint Online, enabling a consistent taxonomy in both platforms. Unlike other hybrid features, taxonomy is unique in that once it is synchronized from on-premises to the cloud, it should only be managed from SharePoint Online. Hybrid taxonomy was originally released for SharePoint Server 2016 but was later updated so that it was available as far back as SharePoint Server 2013.
Prerequisites
In order to be able to configure hybrid taxonomy and content types, the following prerequisites must be met:

- The Copy-SPTaxonomyGroups, SPO365LinkSettings, and Copy-SPContentTypes cmdlets are available.
As a reminder, all hybrid SharePoint features rely on Active Directory...
