Upgrading

If you already have a DotNetNuke portal and would like to upgrade from version 3.x to version 4.x, a few steps are required. The amount of modification you have made to your installation will affect the amount of time required to complete your upgrade. Since there are distinct changes to the structure of the DotNetNuke files, the best resource for upgrading your site is the DotNetNuke Installation Guide, which can be found on the downloads page once you download the Documents Package. This will walk you through the steps necessary to upgrade your site.

Upgrade Checklist

While upgrading, there are a couple of things you will need to be aware of:

Do you have any custom modules, either built by you or purchased? Since versions of DotNetNuke above version 4.0 employ a few changes to the module structure, some of these custom modules may no longer work. You will need to check to see if an updated version of the module is available and upgrade each module.
Have you made any modifications to the core architecture in the previous version? Since we will be using the code from the new ZIP file, any changes you made to the old code will no longer be available. You will need to redo those changes in the updated framework after you update the files. For this reason, it is strongly recommended that you make no modifications to the core architecture itself.
Make sure you DO NOT overwrite your old web.config file! One of the reasons that the web.config file is named release.config in the install package when it is downloaded is so that you do not accidentally overwrite your current web.config file. You will need to make sure that the MachineKeys in your new web.config file are exact copies of the MachineKeys in your old web.config file. If these are incorrect, your site will not work.

So if you have not done much to your site except use the standard modules then the steps to upgrade are fairly straightforward.

Back Up Your Database

For the Management Studio, click on the Start button, and go to Programs | Microsoft SQL Server 2005 | SQL Server Management Studio. Sign on to your server and drill down the (local) server by clicking on the plus (+) signs, right-click on Databases, look for DotNetNuke, and right-click on it to bring up the menu. Select Tasks and Backup to begin the backup procedure.
On the General tab, leave all the default settings and click on Add. In the File Name box, enter the location where you would like the backup saved and fill in a name for your backup.
It is common to put an extension of .bak at the end of the file name, but here it is not necessary. Click the OK button on the Select Backup Destination dialog and then click OK again on the General tab. You will receive a message box when the backup completes successfully.

Back up Your DotNetNuke files

Whenever you are about to make changes to your site it is always a good idea to back up the physical files located at C:\DotNetNuke. Make a copy of this folder and store it in a safe place. This will allow you to revert back to your old site if something goes wrong.
