Upgrading via GUI
This section describes the upgrade procedure through the FortiWLC GUI.
Notes:
- Standalone controllers running images prior to version 8.3.3 (except version 7.0-12) are required to upgrade to 8.3.3 GA and then to the current release version.
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.
- To upgrade controllers using GUI, navigate to Maintenance > File Management > SD Version.
- Click Import to choose the image file.
Note:
Direct upgrade to the current release version using the .fwlc format is supported only from release 8.4.0 and later. Upgrade from pre-8.4.0 to the current release version using .fwlc is not supported.
After the import is complete, a success message is displayed.
