I am moving several sites from a dedicated server over to Amazon AWS and so far everything is great. I have a couple different DNN installs each with a single portal/site on my EC2 instance so far and they work great.

Next to move is a DNN install that has 3 separate sites/parent portals on that one install. I have not tried to move it yet, and think I may have a problem with the multiple sites on one dnn instance because a single EC2  instance only has one IP address, and that isn't even the same as the elastic IP I am using. I believe this install is older - probably dnn 5.x.

Since I cannot use a separate IP address for each dnn instance/website I am using the host name part in IIS which works fine for the single site dnn installs, but now that I need to do a multiple site dnn install I don't see how it will work - what will I put in the host name in IIS?

hmm... I wonder if I can create a new site in IIS for each parent portal, set their host name to the site name and then have it point to the same folder that has the one install. That almost seems like it will work.

Sorry to ask questions before actually trying, just hoping someone knows if it can be done before I give it a try tomorrow.
