Important Upgrade Information

Flashing Notes

• Full chip erase REQUIRED when upgrading from 8.x
• Back up your configuration with diff all before flashing
• Review 9.0.0 Release Notes for breaking changes and incompatible settings

Incompatible Settings Changes

The following CLI settings have been renamed or changed in INAV 9.0. When loading an older diff all, these will show errors:

Renamed Settings:
osd_pan_servo_range_decadegrees replaces the name of the old osd_pan_servo_pwm2centideg

• Check the 9.0.0 Release Notes Wiki for further information

Migration Instructions:

1. Export configuration from 8.x: CLI → diff all → Save to file
2. Flash 9.0.0 firmware with Full Chip Erase
3. Review and update your saved diff for any renamed/removed settings
4. Load edited diff into new CLI
