You can save the update files either directly on the UMS server or you can put them on your captive FTP server. If you have many devices to be updated, you should work with the FTP server because it makes it easier to distribute large amounts of data in the local network.
No Downgrade from IGEL OS 11.03
It is not possible to downgrade from IGEL OS 11.03 or higher to any version before IGEL OS 11.03, except IGEL OS 11.02.200. This is because, from IGEL OS 11.03 onwards, the system partitions are signed to guarantee their integrity; it is not possible to change from a system with signed partitions to a system with unsigned partitions. IGEL OS 11.02.200 is a special variant of IGEL OS 11.02 that has signed system partitions. IGEL OS 11.02.200 is only available from the IGEL Support Team.
