Hi:
I'm trying to downgrade a 7210 controller from 6.4.x to 6.3.x, so that I can join it to my existing cluster of controllers. (will upgrade all to 6.4.x, once the 3400's are retired).
But when I use the GUI to upload the new image, the image file appears to upload, but then I get the message:
Error determining new default boot partition version.
And that's all. nothing else happens. This message occurs regardless of which partition I try to use.
Ideas?
Thanks,
Tony
