I've recently taken over the management of one of our internal web servers and discovered that it needs some major updates.
I will be upgrading the OS this weekend from 2008 to 2012 R2. It's not the best way to do it but we don't have anyone in house with any DNN knowledge so building a new server and moving the content is not an option at the moment.
This being said, I also need to get the DNN platform updated as much as possible.
There was a review done by an outside company a couple of years ago that advised we can safely move to version 7.04.02 and have our custom modules continue to work properly. A newer version would be better but I know this one will work and it will meet our security requirements.
So far I know I will need to step through multiple version upgrades because we have custom modules and I can get the upgrade packages from GitHub. What I don't know is:
1) What version I need to move to at each step in the upgrade?
2) Are there any quirks or things I'll need to modify at each step to make sure things continue to work?
Would someone be able to help or provide me with some guidance?
Thanks in advance!
