When an MGOS gateway is redirected to a different AMM — whether manually or via DNS — it initially appears in AMM as a transient gateway, identified by a placeholder ID in the format DELS-XXXXXXXXXX.
Once the gateway is rebooted, it sends a boot event to the AMM, which then replaces the placeholder ID with the gateway’s actual serial number.
The MGOS router must be rebooted immediately after redirection to a new AMM — the same day as the migration, if at all possible. Skipping or delaying this reboot will result in data loss.
