SPSTrust - SharePoint Trust Farm Tool

It follows the Microsoft guidance Share service applications across farms in SharePoint Server and is compatible with SharePoint Server Subscription Edition.

Note

SharePoint Server 2016 and 2019 reached end of support on 14 July 2026. For those versions, use the previous major release (v2.1.0).
