Move to Group

What
The Move to Group command moves a selected device or group to another group. It is related to Copy to Group, but it changes the object's current group placement instead of adding another membership. Objects that come from Smart Groups can be copied, but not moved, because Smart Group membership is controlled by criteria.
When/Why
Use this command when you are reorganizing static groups or moving device records into a different location. Check assignments first: moving a device can change which Filesets, profiles, or deployments it receives when those items are assigned through group membership.
Quick answer: Move to Group changes the selected object's group location. If you only need the device to appear in an additional group while keeping its current placement, use Copy to Group instead.
How
Use the ellipsis (
) to the right of the device in View - Devices, then select Move to Group... and choose the destination group.
