Updated successfully via MongoDB migration to 8. These were the steps: -Backup your settings at Omada controller --> Maintenance -Stop controller, adjust the following command if necessary (i.e. path) and run it: docker run -it --rm -v /mnt/user/appdata/omada-controller/data:/opt/tplink/EAPController/data mbentley/omada-controller:mongodb-upgrade-3.6-to-8 Then go to the Omada Controller Docker and change tag to i.e. mbentley/omada-controller:6.0, wait and it should be updated. Thanks mbentley 😃.
