XOS upgrade question

[Kar_Del_Moral]

We have our big maintenance window on a weekend, I need to upgrade the XOS image on several devices, can I pre-load the image and install the new image on the non working partition before the schedule window, so then I can just reboot with the new software (without causing any disruption on the service)? or should it be only download not install?

This will work fine Karina. The default will be to boot the image that has been uploaded, so if you want to be sure it does not come up on an unscheduled reboot (like a power loss), you'll need to enter "boot image xxx" where xxx is the partition to use. You can set it to continue using the "current" image, then before your window set them to the opposite image and reboot when ready.

sorry "use image xxx" - would not let me edit inline...

You can download and install. Then just set a reboot time for your maintenance window.

Have you tested the intended code on a subset of stacks in your network?

I like to install new code on one stack and let it run a few days. Then install on a group of stacks for a few days before rolling it out network wide.
