During this upgrade process your MQTT broker will be offline.

If you are performing license deactivation/reactivation online, then typical update time is less than 10 minutes.

If you are performing license deactivation/activation offline, you will need to send the deactivation/activation requests to support@cirrus-link.com in order to receive the Activation Code required to complete the upgrade. Cirrus Link support hours are 8am - 5pm PST. To minimize downtime during your upgrade, we recommend letting Cirrus Link know ahead of time so we ensure support availability during your upgrade period.
