When I am upgrading from to following the Cotroller ask for more files.  What other files I need in add to *.aes file?

I check this at "Step 18  After the controller reboots, repeat Step 6 to Step 17 to install the remaining file."

This is procedure:

I think the is no need for more files.

Thanks in advance.

merhabalar ben modem hızlanması ve yeni güncellemeleri yüklemek da yazılar gözükmüyor ve daha anlatımlı bir video lazım.

When is Cisco going to bring the WLC upgrade process up to par with other products like the ASA or ACE where you can upgrade one device at a time? 0 down time is what management is asking for these days.

If there is a road map for this please let me know and if there isn't please consider this a feature request.

Thank you Rajesh for that demonstration. For a very short process there are a couple of trip hazards that I can see. 1. Cisco uses a variety of methods to reference the source tftp image location. With it in the default "Root" we are seeing simply "." 2. At the end of the process there may be differing instructions for different models. Recent reading shows the CT2500 Range to require the "reset system" keyword to save the download and reboot the device. The reload command will remove the image that has been download to RAM only and restart the device with nothing to reference in NVRAM. (In support of a very useful video, which is now in my reference list, thank you)
