Everyone isn’t a real role.. why are you trying to export it? it will be in the other env.
Valuable hint, thank you Bill. The problem is, it is used in the ACL Policy and thus will be exported, i.e. my ACL Policy has a reference to Everyone, which I need (somehow) to "resolve".
In the end I must add e.g. Everyone.ServerGroup.Read during import in the other environment for the ACL Policy over there.
?how are you doing the exports? i think you can add 'Everyone' by name...
