Is it possible to save mxd to a previous version with ArcGIS Engine?

Question

This is a post of a way to programmatically save an mxd to a previous version using ArcGIS Desktop.  However, I was wondering whether there is a similar functionality for engine?

That's pretty much what I said to do:            Dim mapDocument As IMapDocument = New MapDocument
            mapDocument.Open("C:	emp\myMap_v10.mxd")
            DirectCast(mapDocument, IDocumentVersion).DocumentVersion = esriArcGISVersion.esriArcGISVersion93
            mapDocument.SaveAs("C:	emp\myMap_v93.mxd")
            mapDocument.Close()

True, but you would probably need to open existing MXD, change version and save it as new version?

You should be able to QI from IMapDocument to IDocumentVersion, set the version property and save.
