Recover deleted devices in cnmaestro

Is it possible to un delete a device from cnmaestro? We are missing some 30 devices from our network which might have been deleted on by our old tech from cnmaestro.
Can cambium provide us with a list of deleted devices from our cnmaestro account?

You can check the audit logs

Go to application > audit logs

apply the following filter

Module : select device
Action : select delete.

You will get the list of deleted devices.

Unfortunately Vijay the audit log only appears to go back about a month or so. Is it possible to get data before that?

cnMaestro cloud retains the last one month logs only as of now, there are plans to increase the storage for more than one month in the upcoming releases.
