I believe it is possible, but the UI is missing. See https://github.com/jupyterhub/jupyterhub/issues/1390.
I'm unsure if you can run both _at the same time_ or if users will need to choose one, and stop it before opening the second. IIRC the hub should not really care what is running in the back though, so it should be possible to run a 5.1 and a 4.x next to each other. -- M On Tue, Nov 21, 2017 at 5:01 PM, Jason Moore <[email protected]> wrote: > Hi, > > I invested in using JupyterHub to teach two courses this year (which has > been great!).
