I have already 2 Domains using in my dnn portal.

The default portal uses  lets say www.url1.com

The secound parent portal uses www.url2.com.

Now what I must do; and am not sure with certainly HOW TO and if it will work is this:

The url for portal 2 (www.url2.com) should now point to porta1 one.  This means that portal 1 should use 2 www.-aliases, I don't know if this is possible at all?

And some alias like "en.url2.com" should be used for the parent portal 2. Could it be that simple to simply delete one alias and add anothe one? Or there are something special to consider here? In which ordet I shoule do this`? Does it matter?

Thank you.

yes, a site can have multiple portal aliases.

I would first of all configure site 2 with the new URLs you require and then delete the old URL. Once you have done that add the old URL to the portal alias for site 1.

It should be ok, just take it one step at a time to make sure that each change you make still works.

Thank you Lee, it was a big help for me.

Following the tutorial 17, I've got some other problems and don't know what to do? The CP interface of different Webservers are very different. I have already tried on 3 different webservers, and DNN can't access to the created parent/child portals: On one of them I created a subdomain, it didn't work. I asked the support, the guy there just wore me "I created a domain alias for the subdomain you needed give it a few hours and it should be good to go.", there are already 24 hours passed. I tried on another server, this time I had the option to choose with or without www. Okay, I selected without and the created subdomain http://xx.yyyy.com is been created but DNN can't navigate to it again, entering the url on the browser this page appears:
"This is the page that appears:This is the placeholder for subdomain xxx.yyyy.com. If you see this page after uploading site content you probably have not replaced the index.html file.

This page has been automatically generated by Server Administrator. "

On the third Webserver, it was just possible to create a www.xxx.yyyy.com. DNN can't navigate to it and once I enter the url in the brrowser it says:
"If you see this page, means that your website is successfully installed on our server.

Steps to have your first website up and running.
....."

On tutorial 17 once you create a subdomain it runs immediately. Is it the usual way? Or you had to wait too? The support people are sometimes funny, and don't want to say how to? Or what is going on there? Their konwledgebases are very often outdated, and the UI of their CP is very different than Reseller Choice.

I am on the end of my nerves. Do you maybe have any advice for me?

Thanks

Your domain need to be "pointed" at the IP address of your webserver.   This is needed so that requests for your site are pointed to the webserver where DotNetNuke lives.

DotNetNuke needs to be configured so that the domain name is also in the portalalias table.  This is so that DotNetNuke can direct requests that get to it from the webserver to the correct portal.
