I have 24 routers I need to upgrade the firmware on. They all use the CF card for the firmware and of course there is not enough space for 2 images on the card. I see a few ways to do this, but was wondering how you handle this task.
A) SSH to router delete exiting image file. Upload new image file reboot. Drive to site if there is an issue.
B) Drive to site, replace CF card with a card containing the new image.
I'm not excited about these 2 options.
What am I missing?
