New upgrades of DNN are released on a regular basis by the DNN Corporation. These may be introduced to improve performance, add additional core functionality, take advantage of modern browser behaviour or to patch the older version against unwanted attacks. Whichever of these is relevant to your business, regular upgrades are vital to the success of your DNN website.
The process of upgrading to a new version of DNN may seem to be fairly straightforward, but there are risks attached and problems to overcome. Existing off-the-shelf DNN modules such as sliders, banners, forms and blogs may not always work with the new upgrade, therefore if new modules are needed then a different licence or indeed module may be required.
At worst, a company may find that its attempts to install the upgrade have caused its website to break and valuable content to be lost. At the very least, they could find the upgrading process time-consuming and a hindrance to their core activities.
