Upgrading DNN can be a very complex process. If you haven't kept your DNN version upgraded since you deployed it, you may have to apply a series of updates, and there are very specific upgrade paths you need to follow to avoid problems. There is a usually recommended upgrade path which may require multiple version "hops", intermediate version upgrades you need to apply to get from the version on your site to the most current version available from DNN. Making sure you have the proper backups before tackling this, sorting through the right upgrade path, and actually performing those multiple "hop" upgrades to your DNN installation can be a daunting task. Not to mention handling a failed upgrade - which may be a simple module or skin unload, or may require rolling back upgrades you just applied. For those technically inclined and interested, they see it as a challenge. But for the rest of us who just want someone else to take care of it for you, 3Essentials has good news... we're now offering DNN Upgrade Services for our customers!
