Have any other organizations with a large user base (15,000+) and number of groups had issues upgrading to Confluence 3.5.1 or Confluence 3.5.x?
What steps or solutions were taken to overcome the obstacles in Atlassian's recent *change in user management (*Embedded Crowd)?
We are looking for solutions that we could easily leverage without using unsupported third-party tools and developing custom scripts.
Any advice on a Confluence 3.5.x or 3.4.x upgrade?
