It could be a bug.  This version is a special engineering release. 

Try to upgrade to, say, 7.0.252.0 and see if this works.  If it does, then go straight to 8.3.X.

I have upgraded to 8.2.121.0 first and it was gone properly. then i upgraded to new version. now its OK. :)

Thanks for the update & happy to see it's finally working.

Install the latest goldeals star version which I believe is still in the 8.0 family.  I just installed it last week and it's fine.

HTH,

Bob

I got the same error when trying to update a pair of Cisco AireOS 3504 in HA-SSO setup running SW version 8.5.140.0.

I wasn't able to upgrade to 8.10.130.0, 8.5.161.0 or 8.5.151.0 ... I got always the following error message:

Transfer Failure: Version mismatch - the image version is not for this model.

I noticed that the uptime was more than 600 days, so I just rebooted both controllers (GUI: Commands->Reboot->both), and then the problem was gone. I was able to load the newest 8.10.130.0 image without any trouble.
