Here at Bobcares, we often receive requests regarding DNN upgrade as a part of our Server Management Services.

Today, let’s see how our Support Engineers help our customers to upgrade the DNN without breaking the website.


Why we need a DNN upgrade?

Upgrading the DNN website to the latest version increases the website functionality. Let’s now check the main reasons for the DNN upgrade.

Its a proven fact that good websites increases the visitors to our website. So updated DNN versions helps to make the website more beautiful and help us to ensure a successful ranking on all search engines.


Suggested DNN Upgrade Path

Many of our customers asks us the possibility of the DNN upgrade directly from version 7 to version 9. Here, our DNN Experts always suggest them to upgrade it only in the correct path, without skipping any versions.

The skipping of the DNN version breaks the whole site. So we recommend the below upgrade path for our customers.

From Version       To Version 

02.00.04              02.01.02
02.01.02              03.01.01
03.01.01              03.02.02
03.02.02              04.03.07
04.03.07              04.04.01
04.04.01              04.06.02
04.06.02              04.09.05
04.09.05              05.04.04
05.04.04              05.06.08
05.06.08              06.02.08
06.02.08              07.04.02
07.04.02              08.00.04
08.00.04              09.01.01
09.01.01              09.03.02
09.03.02              09.04.04


If the current version of the DNN Platform is between any of the versions listed above, then we first upgrade the DNN  to the closest listed version.

For example, if the current DNN version is 09.02.00, then we upgrade first to version 09.03.02 and then to 09.04.04.

On each upgrade, we take the backup of the site files and database. If any error occurs in the next upgrade, we can easily revert it back to the previous version from the backup.
