Getting Started with Upgrade
The following table describes the approved upgrade path applicable for all controllers except the new virtual controllers.
Note:
In pre-8.4.3 releases, if the MAC-delimiter is set to hyphen in the RADIUS profile for 802.1x authentication, the controller sends the called station id with MAC-delimiter as colon. When you upgrade from pre-8.4.3 to 8.4.8, if there is a RADIUS reject for the MAC-delimiter, then reconfigure the RADIUS server.
FortiWLC-1000D and FortiWLC-3000D controllers can be upgraded only from 8.3 releases.
From FortiWLC release... |
To FortiWLC Release... |
---|---|
8.4.0, 8.4.1, 8.4.2, 8.4.3, 8.4.4, 8.4.5, 8.4.6, 8.4.7 |
8.4.8 |
Note:
- Fortinet recommends that while upgrading 32-bit controllers, use the upgrade controller command instead of the upgrade system command.
- Controller upgrade performed via CLI interface will require a serial or SSH2 connection to connect to the controller and use its CLI. FortiWLC-1000D and FortiWLC-3000D and 64-bit virtual controller upgrades can be performed via GUI as well.
- Upgrade the FortiWLC-1000D and 3000D controllers with manufacturing version prior to 8.3-0GAbuild-93 to version 8.3-0GAbuild-93 and then to the later builds.
