Presently our application has been deployed in Alfresco 4.2.2 Enterprise version.We want to move our application to 5.x Alfresco version.

What are all versions released so far in 5.x?Initially I want to test our application in all 5.x Community Versions that are released so far.Where can we download old & new 5.x Community Versions?

What are the new features added in 5.x w.r.t 4.2.2?

You can find Alfresco Community releases at https://wiki.alfresco.com/wiki/Category:Release_Notes

That "2016NN GA" are 5.1 versions.

However, you can also download all Enterprise versions from support.alfresco.com

From 4.2.2 Enterprise, you have to upgrade to 5.0.2 and then you can upgrade to 5.1.0 (http://docs.alfresco.com/5.1/concepts/upgrade-path.html)

As an Enterprise Customer I suggest you to try the latest version of Alfresco One on a dedicated machine, actually should be Alfresco One 5.1.1 as Angel Borroy​ wrote above. This will avoid any specific issue about environments compatibility and using the latest service pack provided by Alfresco. I mean you will not spend your time resolving existent issues reported in the Community version.

Notice that you can use the 30-days trial license that is automatically generated when you start for the first time Alfresco One and in this case you are totally supported by Alfresco Engineers for any questions or information about how to migrate your instance in the better way.
