As long as the miner's antenna is plugged into GNSS, even if the upgrade is done and not
yet updated, it will continue to run as a dual band miner until the update and receive
rewards.
In the map of the console, you can see when the device has been updated or the ticket for
the update has been closed.
Therefore the interruption during the installation of the PCIe card as well as the reconnection
of the antenna, should only be short-term and have minimal effect on the rewards.
Please open a ticket if you are experiencing trouble after the upgrade.
