Update DNN4x to Dnn 5x

Hi another stuff that i done recently is really cool and i hope it help lot of DNN professionals

Upgrading dot net nuke

Its simple but you must need the dnn4.8 or later version for updgrading if you are planing to move your dnn 3 or 2 in to dnn 5 then you must upgrade the 3 to 4 and then then 4 to 5

here i just define the upgrading from 4 to 5
Backup Existing Site
Although the XML Merge functionality and DotNetNuke 5.0.0 have been tested a great deal it is VERY, VERY important to take a full site backup before completing an upgrade. This is especially true when going from a 4.x to 5.x installation, due to the massive changes introducted in DotNetNuke 5.0.0. If you are unsure of the process to backup your site, please be sure to read my blog How to Backup a DNN Site, additionally if on a remote hosting provider you can contact your provider for assistance creating the backups.

NOTE: DO NOT CONTINUE if you have not validated a 100% correct backup file. I have tested multiple 5.x upgrades, and there have been limited occurances where sites have had issues, I cannot stress the importance of backups enough!

Upgrading Site
To perform an upgrade from 4.6.2 or later to 5.0.0 you may simply download the UPGRADE package for the 5.0.0 version of DotNetNuke from the website. You MUST use the upgrade package for this process. Once you have downloaded the package, simply unzip it over your existing DNN installation. This will update all DotNetNuke core files and prepare you to install the upgrade. (NOTE: Release Candidate versions of DotNetNuke 5 are NOT to be used for production sites)

Now, simply navigate to and you will be triggering the upgrade just like normal. All needed web.config changes will be merged and your site will be upgraded. If you encounter an under contruction page, simply try the URL again. After a few moments of processing you should see a success message. If any errors are encountered you will want to be sure to note them BEFORE continuing on to another page.


Some error arrives after updgrading the dnn4 to dnn 5

make sure in your module section there will not any module with the duplicate name if any module with the same friendly name present then it gives and error

make sure you select the language in the site settings you will set the default languge english under the languge option other wise site settings give an error

Calling LoadLibraryEx on ISAPI filter “C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll” failed

Dear Readers
if you get the error

Calling LoadLibraryEx on ISAPI filter “C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll” failed

Here is the solution 
Get a command prompt in administrator mode and go to C:\Windows\Microsoft .NET\FrameWork64\
and run aspnet_regiis -r. This will re-register the right libraries. It has happened twice already to me.
For other frameworks (32 bit or other versions of .net make sure you go to the correct folder (i.e. Framework/, etc.)

xxxx is the the number which is present with the folder name so i suggest you guys to check the folder name in your directory

If "run aspnet_regiis -r" is not working and if you get the error run is not recognized command then just type " aspnet_regiis -r" it will run fine

Reason of problem
Your frame work has been change may be you have install the lower version on the higher version or may be because of any reason you have register another version in your IIS, in my cas…
