Hi Michael,
It seems that after selecting and triggering one group of APs for pre-load, you can actually select a second (third, fourth, etc.) group and trigger pre-load even though the GUI displays a message saying a reboot is required in order to trigger pre-load for more APs. If you log in to CLI, the second (third, fourth, etc.) AP group chosen will in fact be preloading and the process works without a reboot despite the GUI message.
I do agree with you that it really doesn't make sense to be preloading only a subset of APs, but if someone clicks something by mistake or is unfamiliar with the pre-load process, this GUI message can be misleading to them. I only commented on the thread since the original poster was on 6.4.x / 6.5.x and I had the same message on 8.7.x. (it is also nice for others who may be searching this error message to get some closure). The clarification that this is expected behavior is appreciated.

I don't agree with it but that is expected behaviour. Once you trigger an ap-preload for a particular ap-group, you cannot choose any other groups, unless you go ahead and reboot the controller first.
The lesson here is to preload all APs. To be honest it doesn't make a lot of sense only preloading a subset of them.

Hi,
Yes, it does not make sense to reboot the controller to do AP image-preload.
It maybe bug of your current software version.
Please try to use CLI "#ap image-preload add AP-Group OR AP-name and activate"

Hi,
we have a controller which runs 6.4er Version and i want to upgrade to 6.5. On t he comtroller there are 1500 accesspoints connected so i want to preload the image.
I tested with just one ap. It worked perfectly.
But no i want to do the preloading on all aps but i got the errormessage:
An AP image preload has already been executed. You must reload the controller before executing another one.
That does not make sense at all i cannot reboot the controller now. I wanted to reduce downtime with preloading and now I should have more downtime?
Is there a way to get it working again?
