I have seen that you have migrated the wiki section completely.
Should it only be an archive to get information from? If yes, how to ensure that the content is valid?
We did migrate the entire Wiki to the new Jive platform. Those articles now live as documents in Jive. While some things in the Wiki are current, the things that are not have been marked Outdated. You should be able to tell which ones are outdated by the pop up. We decided to bring that content over, as many people use older versions of Alfresco, so while the content is technically outdated, it is still useful to some users. The content is valid - it's probably just valid to a specific version of Alfresco.
