I'm in the process of upgrading my website from 5.5.1 to 7.3.3 using DNN's suggested upgrade path. I'm currently on 6.2.9 awaiting confirmation that we can upgrade my .NET Framework from 3.5 to 4.5. Right now, 6.2.9 isn't working well at all and I'm hoping 7.3.3 will fix this.
If I do successfully upgrade my .NET Framework to 4.5 and DNN to 7.3.3, but it breaks too many costly things (skins, modules, etc), I will have to revert back to 5.5.1
My question is: will DNN 5 still work on .NET Framework 4.5? I understand that DNN says it will work, but those same specifications say the recommended environment for DNN 5 is .Net Framework 3.5.
The better question might be: what is the real difference between these Frameworks when it comes to DNN and what can I expect if I need to run DNN 5.5.1 on .NET Framework 4.5.
