Add a dummy alert rule with a virtually always true condition (e.g. Device Status with Available Memory >= 1K ) and action "Relocate Device(s) to"  your target directory.

I don't see an option that would be good for me in relocate devices. I would like to do this based on the imei or device name.

If you have some device name or IMEI pattern to select devices of interest, use them in either one of the following ways:

1. Use the pattern(s) in device filter for MobiControl to search all devices matching the pattern(s), then select all or multiple devices (at most 250 devices per page), and drag them to the target sub-group

2. Use the pattern(s) in virtual group definition for MobiControl to automatically include them in the virtual group, then apply a dummy/triial file-sync rule (e.g. Device Status with Available Memory >= 1K) to this virtual group with action to auto relocate all devices to the target sub-group.

Another good option is to use the API of Mobicontrol. We have used that method to move devices when the amount is large.

thanks, i used api and it's works.
