I have been tasked with updating Confluence from 3.2 to 4.x. Note that we use Crowd for User Management and SSO, and we have an external DB. I successfully migrated our PROD 3.2 version to a TEST environment (pointing at the existing Crowd) and then successfully upgraded that to 3.5 (as the instructions say you can't go straight to 4.x <sigh>). All was well. When I went to update the plug-ins in that 3.5 environment, something went wrong because Crowd stopped working and now the browser just hangs and spins eternally. I thought it might be something in the seraph-config.xml but I have tried every combination I can find; nothing works.
What I want to know is, can I install a virgin 4.x copy and import what is needed from the old 3.2 copy? Where can I find *complete* instructions for doing something like that?
