Hi,
Does anybody know if it is possible to downgrade a WLC by dowloading a lower version of the code ?
Or does this depend on the versions ?
Thanks,
Gerard van Bon

Hi Gerard,
You can Downgrade the WLC Release Version, but be careful of this note;
Caution: If you require a downgrade from one release to another, you may lose the configuration from your current release. The workaround is to reload the previous controller configuration files saved on the backup server or to reconfigure the controller.

The only rstriction I have seen to downgrading is with some of the Mesh Releases. You can see the details here;

Hope this helps!
