Hi,
I've a cluster with 2 IAP-225 and 2 IAP-315 running firmware 6.5.1.0-4.3.1.2
I would like to downgrade the APs to 6.4.4.8-4.2.4.6.
I tried to upgrade all together, and even just the 315 - but I alwasy get image verification failed. If I only have the 315 in the cluster and I try the uploading local file (instead of tftp), it says "invalid image file".
I was able to downgrade to 6.5.0.0-4.3.0.0, however, any firmware below that - the verification fails.
The log is empty.
