Tip

Upgrade Notes: DotNetNuke has been around since 2002, and in that time has had a number of changes which can complicate matters during the process of upgrading through different versions. These include:

Requirements Changes & Prerequisites

  • The changeover from DNN 3.x to DNN 4.x - DNN 3.x used ASP.NET 1.1, whereas DNN 4.x and above require ASP.NET 2.0
  • Editions prior to 4.6.2 - Prior to 4.6.2 site admins had to manually merge a number of key fields in web.config such as the machinekey and both connection strings. With 4.6.2 DotNetNuke introduced functionality known as xmlmerge which automatically does the web.config merging on your behalf.
  • 3.02.02 - 4.03.07 - Please refer to the Detailed installation guide "Upgrade to DotNetNuke 4.x chapter". This blog post also contains information about upgrading from 3.2.2. to 4.x: Preparing for an upgrade
  • DotNetNuke 5.2 - This version introduced the requirement for SQL 2005 and ASP.NET 3.5 SP1
  • When upgrading from a version before 5.3.0 to after 5.3.0, you may encounter this error during the upgrade: “Type 'Web.HttpResponse' is not defined.” This error primarily occurs if an the XML module is already installed. To prevent this, please check PRIOR to upgrading if the XML module is installed in your DotNetNuke version. If it is installed, please upgrade it PRIOR to upgrading DotNetNuke to version 4.3.5, available on DNN.XML Module on GitHub
  • With the 7.0 release DotNetNuke has some additional changed pre-requisites, please see the DNN 7 Developer Quick Start for further details.
  • In DNN 9.2.0, multiple APIs were removed that were marked deprecated in DNN 7 and before. Most of the core modules have been updated since and you can find them at https://github.com/dnncommunity. If you have other modules installed, please check for updates before upgrading to DNN 9.2.0 or later
  • DNN 9.4.0 introduced a minimum requirement of ASP.NET 4.7.2
