Symptoms
When migrating a site collection with the In-Place Hold Policy Center or the Compliance Policy Center template, ShareGate Desktop shows numerous errors.
Details
In-Place Hold Policy Center and Compliance Policy Center are two new site collection templates available in SharePoint 2016 and in Microsoft 365. They contain lists that affect other site collections, like policies for site collection deletion, which are not currently supported by ShareGate Desktop. Therefore, the migration of any site collection with any of those two templates is not currently supported by ShareGate Desktop.
