There's no way for you to do this going from 3.8 to 4.0 at the moment. > The insert action on the rt-setup-database script mentions a > supplementary datafile. Could this action be used to perform the > incremental upgrade I describe above? No, that datafile is an "initialdata" file and can't be used to do the incremental migration you describe above. (If you're curious what it *can* do, see etc/initialdata or etc/upgrade/*/content for examples. There's newly written doc on initialdata files here: https://github.com/bestpractical/rt/blob/4.0/document-initialdata/docs/initialdata.pod)
