Hello,

When I try to upgrade from 4.8.2 to 4.8.3, I receive the following error message (I done plenty of other migration without any problem):

DotNetNuke Configuration Error

Domain Name "mydomain.com/Install" Does Not Exist In The Database

DotNetNuke supports multiple portals from a single database/codebase. It accomplishes this by converting the URL of the client browser Request to a valid PortalID in the Portals database table. The following steps describe the process:

1. Web Server Processing
   
   • When a web server receives a Request from a client browser, it compares the file name extension on the target URL resource to its Application Extension Mappings defined in IIS.
   • Based on the corresponding match, IIS then sends the Request to the defined Executable Path ( aspnet_asapi.dll in the case of ASP.NET Requests ).
   • The aspnet_isapi.dll engine processes the Request in an ordered series of events beginning with Application_BeginRequest.
2. Application_BeginRequest ( Common.Globals.asax.vb )
   
   • The Request URL is parsed based on the "/" character
   • A Domain Name is constructed using each of the relevant parsed URL segments.
     
     Examples:
     
     URL: http://www.domain.com/default.aspx = Domain Name: www.domain.com
     URL: http://xxx.xx.xxx.xx/default.aspx = Domain Name: xxx.xx.xxx.xx
     URL: http://localhost/DotNetNuke/default.aspx = Domain Name: localhost/DotNetNuke
     URL: http://www.domain.com/virtualdirectory/default.aspx = Domain Name: www.domain.com/virtualdirectory
     URL: http://www.domain.com/directory/default.aspx = Domain Name: www.domain.com/directory
   • Using the Domain Name, the application queries the database ( Portals table - PortalAlias field ) to locate a matching record.
     
     Note: If there are multiple URLs which correspond to the same portal then the PortalAlias field must contain each valid Domain Name in a comma seperated list.
     
     Example:
     
     URL: http://localhost/DotNetNuke/default.aspx
     URL: http://MACHINENAME/DotNetNuke/default.aspx
     URL: http://xxx.xx.xxx.xx/DotNetNuke/default.aspx
     PortalAlias: localhost/DotNetNuke,MACHINENAME/DotNetNuke,xxx.xx.xxx.xx/DotNetNuke
     
     Note: If you are installing the application to a remote server you must modify the PortalAlias field value for the default record in the Portals table according to the rules defined above.

If anybody has an idea (maybe degrading to an older version to re-do the upgrade process ??? Is this possible ???)

Hello Sebastian,

Thanks a lot for your concern and answering.

That's what I done several times yesterday: deleting the database, restoring files, and re-trying the upgrade process... Without any success, always the same problem. I even tried Nina advice, without much success neither. For information, I done this procedure several times in the past, without any trouble...

Here is the procedure I follow, it might help you to tell me if I done something bad:
1/ backup DB (4.8.2)
2/ unzip files locally on my computer (I tried DNN 4.8.3 Install and DNN 4.8.3 Upgrade as well / Same result)
3/ add App_Offline.htm to prevent the mess...
4/ FTPing the files to my folder (overwriting existing files)
4 Bis/ Modifying web.config (to reflect the web.config which is provided with the Install/Upgrade pack)
5/ removing App_Offline.htm
6/ accessing my website http://domain.com/Install/Install.aspx?Mode=Upgrade (I also tried Mode = Install, as well as Install.aspx only)

I always have the error mentionned before (DotNetNuke configuration error)... But that's strange, if I access my website, it runs normally, and when I login and access Host Settings, it says that I am running V 4.8.3 !!!!

==> How could I be sure that the whole process went well, without any problem ? And that my version is V4.8.3
I think that 4.8.2 and 4.8.3 are very similar, what are the difference, and how could I be sure that I am safe and relax ???

Thanks a lot for your help Sebastian.
