I am trying to upgrade from v4 to v5 whilst at the same time migrate to a new Mac Mini. I have installed v5.2 on the new Mac Mini (running 10.10.5), copied over the backup from v4 (running on 10.9.5) and imported. All appears to be fine server side however users are missing fonts and in some cases entire workgroups are showing as having no fonts when logged in via the client. During testing with a couple of users this problem was not apparent but as I have moved more and more users over it has become unusable so I have had to revert back to v4 which is a problem in itself as users are now on CC2015. Strangely if I recreate the user as say User 2 and map them to the relevant workgroups they appear to be ok. I have raised this with tech support and am waiting a response but in the mean time wondered if anyone else had successfully migrated to a new server or are having any similar issues?
