Definitely yes.  You can run multiple versions of DNN on the same server.  I basically have all versions of DNN on my server for various reasons.  Obviously each one is installed to a separate physical directory, with a separate Web site, and a separate database for each one.  I created a directory and corresponding database following a naming convention like DNN1010, DNN212, DNN321, DNN441.  When you install ASP.Net 2.0 it will add a new tab to the Web Site definition in which you determine the version of ASP.Net the site will use.  Then, in the Web.config, you define the name of the database corresponding the site in question.

It is really easy if you think about it.

Worked like a charm.

One problem though...I can only access the site on the local machine.  Any other computer gives me a 404 and the url is pointing to the localhost.  There seems to be a post-install networking step that is necessary, but I do not know what it is.  Can you help?

I did add a http alias, but that did not work.
