Important! Consider This Before Upgrading
To make sure that your upgrade can be successful, check the following warnings and notes; a warning symbol indicates that irreversible damage can be done to your devices.
No Downgrade
You cannot restore your IGEL OS 10 system once you have migrated to IGEL OS 11. The device storage is overwritten completely with a new partitioning scheme.
Features (e.g. Clients)
IGEL OS 11 does not have the complete feature set of IGEL OS 10. Make sure that the current version of IGEL OS 11 meets your requirements. For details, refer to the appropriate release notes.
Custom Partitions
The contents of custom partitions will be deleted by the upgrade. Make sure to back up the contents and restore them after the upgrade has finished. Besides becoming dysfunctional after the upgrade, applications and kernel drivers in a custom partition might corrupt the upgrade. For this reason, make sure to first test the upgrade on a characteristic device. We recommend that you disable custom partitions when upgrading; you can enable them once the upgrade has been successfully completed.

The persistence of custom commands cannot be guaranteed. Besides becoming dysfunctional after the upgrade, custom commands might corrupt the upgrade. For this reason, make sure to first test the upgrade on a characteristic device. In general, custom commands must be adapted for IGEL OS 11.
