I need to update the current version of DNN this week. I am currently using 2.1.1. I do not want to do everything twice, so I have a few questions.

5.0 4.9, , 100%, 5.0 .
Honestly, I do not know. But I see that the DNN download page very strongly states that candidates for release 5.0 are "NOT RECOMMENDED FOR PRODUCTIVE USE".
There were a huge number of changes between 2x and 3x, which will lead to almost any custom modules that you need to upgrade or replace. In addition, Mitchell is a DNN man, and I would put him off.
