Perhaps the most significant caveat involves downgrading. If you upgrade to 8.3.150.0 and later decide to downgrade to an earlier release (especially a 7.x release), you will lose your current configuration. The official release notes warn: "If you downgrade from Release 8.3.150.0 to a 7.x release, the trap configuration is lost and must be reconfigured." This is because the configuration structure has changed. The workaround is to either reconfigure the controller from scratch or to load a backup configuration file saved before the upgrade. Always back up your configuration before performing any upgrade.

: Release 8.3 typically supports access points ranging from the older 1140 and 3500 series to the 1700, 2700, and 3700 series.

Do not split traffic across individual 1G ports manually. Enable LAG on the WLC and connect it to a Cisco Catalyst switch using a PortChannel configured for LACP or static trunking. This combines the SFP ports into a single logical 8Gbps pipe, preventing bottlenecking. Radio Resource Management (RRM) 8.3.150.0 features refined RRM algorithms.
