Thank you both for the suggestions and questions: I’ll ask about which version they are using in their office, though I expect it is fairly current. I should clarify this is an architectural to architectural model transfer, not architectural to MEP.
Since she could not edit the RVT format, I exported an IFC format using a generic export format recommended for export to Revit (though the articles on the spec choices is sketchy). She was able to read it into Revit. However, she was only able to use it as a background model. She was unable to modify any elements, but could delete those to be demolished in the proposed design option. Therefore She considered it a bit more useful than the RVT format.
She noted some data came over as well, but it was considered too much work to make use of it, I expect similar the original posting above. I suspect a better data transfer scheme would help, as suggested.
