After upgrading to DNN Version 5.0, I had some problems even though the installation reported Success for all upgrade tasks:

1. Portal Aliases Module Issue
   1. Problem: The Portal Aliases module on the Site Settings page was showing an error and the module couldn't be displayed.
   2. Solution:  Edit the Module Definitions and delete the Edit control, and Modify the location of the View control. The View control should now point to DesktopModules/Admin/Portals/SiteSettings.ascx.
2. Host Settings Module Issue
   1. Problem: The Host Settings module could not be displayed and was presenting an error when I accessed the Host Settings page.
   2. Solution:  Edit the Module Definitions for the Host Settings module and change the path to the View control. Change it to the following path: DesktopModules/HostSettings/hostsettings.ascx.
3. ModuleControls Table Issue
   1. Problem:  After the installation completes, I was having issues with duplicate keys in the Host Settings module. This was caused by some new duplicate keys that were inserted by the upgrade into the ModuleControls table.
   2. Solution:  Delete any records in the ModuleControls table where the ModuleDefID and ControlKey are both NULL.
4. IConBar Control Panel:  An entry with the Same Key already exists
   1. Problem:  I was receiving an error at the top of the page where the Iconbar control panel normally exists that stated that 'an entry with the same key already exists'. This error was in the GetPortalDesktopModules method of the DesktopModuleController.vb file in the Core DotNetNuke.DLL Library. I made the following change (i know not perfect, but it worked for now) to add a Try Catch to the For loop so that if an individual module caused a duplicate issue it would simply be excluded and the remaining modules would still be loaded in the list. Note: I didn't have this issue in DNN V4.9...this only started after the upgrade. The code change is as follows:

Public Shared Function GetPortalDesktopModules(ByVal portalID As Integer) As SortedList(Of String, PortalDesktopModuleInfo)
            'First get all the DesktopModules for the Portal
            Dim dicModules As Dictionary(Of Integer, PortalDesktopModuleInfo) = GetPortalDesktopModulesByPortalID(portalID)
            Dim lstModules As New SortedList(Of String, PortalDesktopModuleInfo)

            For Each desktopModule As PortalDesktopModuleInfo In dicModules.Values
                Try
                    If DesktopModulePermissionController.HasDesktopModulePermission(desktopModule.Permissions, "DEPLOY") Then
                        lstModules.Add(desktopModule.FriendlyName, desktopModule)
                    End If
                Catch ex As Exception

                End Try
            Next

            Return lstModules
        End Function

I hope this stuff Helps you guys. Feel free to use this thread to post any other issues and solutions that were experienced by the upgrade. If I see anything else, I'll post it here.

Thanks,

You can do this through the Host Module Definitions page.
