I want to upgrade the image of the Cisco 2800 series router. Unfortunately, i have to do this remotely as this router is not hosted in my place.
When i tried to copy the new IOS image to the flash, i got the message saying "Not enough memory space in the flash". The only way i have to do this is to delete the old image and copy the new image; then reboot the router with new image.
Since i have to do this remotely, i am really concern about the router down time. Do i have to make any special considerations when i do this?
- When the old image is deleted, will it still allow me to connect to the router to do the new image upgrade?
- Once the image is upgraded, will it boot into normal mode or ROMMON mode?
- Once the image is rebooted, will the old configuration will be still intact? or do i have to reload the config again?
