I have just upgraded my site from 3.2.x to 4.8.4 by following the instructions at http://www.mitchelsellers.com/Blogs/tabid/54/articleType/ArticleView/articleId/106/Upgrading-DNN-3x-to-DNN-4x.asp x The problem is that if I now go to localhost/default.aspx?ctl=login I get an 'object reference not set to an instance of an object' error. The original 3.2 site does not give me this error so I guess something broke after upgradation. - How do I verify if the upgrade was successfull - Is there some sort of a log with a stack trace which I can examine which would give me a clue as to why the login page is not coming up. - Could this be caused by a wrong setting in the machine key in web.config. I have copied the old key to web.config as it is: I notice 4.8 has some new options like validationKey="AutoGenerate,IsolateApps" and decryption="3DES" do I need to merge these in? - Should I compile and run the DNN 4.8 site through Visual Studio 2005 to debug. Is there some documentation on how to compile the solution During upgrade I received an error message saying 04.04.00.log Error:HelpURL The upgrade seemed to have completed successfully though. I looked at the .SqlData file and I found that 'vw_Modules' had been created in my database. Thanks, Deepak.

You might want to try upgrading in several steps: From 3.2.x to the corresponding 4.x version. If you look through the legacy downloads, you'll find the version of 4.x that corresponds to your 3.2.x version. After doing that upgrade, you might upgrade to 4.6.2 before jumping to 4.8.4.

Did you notice this in the instructions from Mitchel: Your DNN Version is 3.3.5 or 3.3.7? Did you do that upgrade sucessfully?

Thanks jncraig. How do I find out the version of my DNN portal and where is this page where I can find the equivalent 4.x version? Could not find anything like this on dotnetnuke.com

Go to the Downloads section and look for the link to Legacy versions of DotNetNuke. You'll be able to find the version of 4.x that corresponds to your 3.x by comparing datestamps.
