Pre-download software to APs with version not on current controller
I am migrating APs from a WiSM running 7.0 to a 5508 that is running 7.4 but I can't find a way to get the 7.4 code pre-downloaded on the APs while they are connected to the WiSM. We're a 24 hour environment so I'm guessing I'll have to migrate one at a time to avoid downtime for users but before planning on this route, which is a pain, I thought I would see if others have found a way to do this.
- download the file 7.4 on WiSM like you do when you want to update it's software (from web gui, under Commands > Download File > Code);
- when done, don't reload the WiSM and issue this command from cli: config boot backup. "This ensures that if a system failure occurs, the controller boots with the last working image of the controller"
- pre-download the new code on APs using the command: config ap image predownload primary <AP-NAME>. You can verify the progress using the command: show ap image all
- when done, change the High Availability configuration on that AP (from web gui, under Wireless > Access Point, then click your AP) and set the 5508 as Primary Controller, then Apply and reload the AP.
Obviously, I suggest you to test this on a non-critical AP :)

The script should be completely self explanatory.
