Follow this procedure to upgrade FortiWLC-50D, FortiWLC-200D, FortiWLC-500D, MC1550, MC3200, and MC4200 controllers. See section to upgrade FortiWLC-1000D and FortiWLC-3000D. See Upgrading Virtual Controllers to upgrade virtual controllers.
- Download image files from the remote server to the controller using one of the following commands:
# copy ftp://ftpuser:<password@ext-ip-addr>/<image-name-rpm.tar.fwlc><space>.
[OR]
copy tftp://<ext-ip-addr>/<image-name-rpm.tar.fwlc><space>
Where, image-name for FortiWLC: forti-{release-version}-{hardware-model}-rpm.tar.fwlc For example, forti-8.5-5-FWC2HD-rpm.tar.fwlc - Disable AP auto upgrade and then upgrade the controller (in config mode)
# auto-ap-upgrade disable
copy running-config startup-config
upgrade controller <target version> (Example, upgrade controller 8.3)
The show flash command displays the version details. - Upgrade the APs
# upgrade ap same all
After the APs are up, use the show controller and show ap command to ensure that the controller and APs are upgraded to the latest (upgraded) version. Ensure that the system configuration is available in the controller using the show running‐config command (if not, recover from the remote location). See the Backup Running Configuration step.
