+The Groups model in Segment is slightly different than in Mixpanel. To explain the conceptual difference, it may help to think in terms of database tables. In Segment, there is a single "groups" table. You can have as many group rows as you want and each row has a unique identifier. When you want to set traits on that group, you only need to know the group id.
 
 However, in Segment you cannot distinguish between "types" of groups. For example, a user can belong to a "Company" as well as a "Team". There is no way to differentiate between those in Segment. In Mixpanel, you can have multiple group types which are defined by a `group key`. To update group traits in Mixpanel you need to specify the `group key` *and* `group id`.

 If you want to confirm, you can configure the new destination to point to a different Mixpanel project and connect it to the same source(s) as the Classic destination and manually verify before fully switching over.
