Hi Eder,
Thanks for contacting Pulseway support.Yes, by default all Linux agents are placed in Legacy group. Currently, the Legacy group is used for the systems which are registered using the Cloud API or the REST API. These systems don't use the Token to authenticate with your Pulseway server, therefore these systems are placed into the legacy group.You can rename the legacy group or the system can be moved from one group to another using the Pulseway WebApp ->Systems-> Systems -> Configuration -> select the Organization-Site-Group in which this system is currently located -> Systems and click on edit -> button 'Move Out' -> select the new Organization-Site-Group and save the changes. For more details about this, please check the following:
