After firmware downgrade and configuration apply are finished on Device 1,
disconnect all Ethernet cables on Device 2. Connect all Ethernet cables back on
Device 1. Now only Device 1 is online and acts as Active role.
Firmware Downgrade on Device 2
On Device 2, follow the same steps in Firmware Downgrade on Device 1 for
firmware downgrade. Go to MAINTENANCE > File Manager > Firmware
Management and upload the old firmware to the standby partition.
Note: Some features in ZLD 4.35 were not implemented in ZLD 4.33, so some
configurations in 4.35 cannot be applied to device with firmware 4.33. Hence, we suggest
you apply the configuration file with ignore error.
