I did a migration from 5.5 to 6.0 and all works fine except a smallish issue. In the activity stream, the user photo do not display (grey icon). Running firebug shows a strange url to get the user's photo : "https://connectionsserver/profiles/photo.do?userid=SYSTEM
" alt="Photo de SYSTEM". Normally, it will use the user's unid.
The same user's photo is displayed correctly elsewhere.
Miss something in the migration process?
