Upgrading via GUI

This section describes the upgrade procedure through the FortiWLC GUI.

NOTES:

• Fortinet recommends upgrading via CLI to avoid this issue which occurs due to file size limitation.
• This issue does not exist on controllers with manufacturing build as 8.3.3 GA and above.
  

1. To upgrade controllers using GUI, navigate to Maintenance > File Management > SD Version.
2. Click Import to choose the image file.
   
3. After the import is complete, a pop message for upgrade confirmation is displayed.
   

Click OK to upgrade; the controller reboots. Click Cancel to abort the upgrade and continue in the existing version.
