Upgrade IOS-XE image pending Reboot.

[Charlie Grey]

for ios-xe, is it possible to be like IOS that we can do all the preparation works (pre-upload the image + setup the boot variable) and only at deseriable time then we proceed with the reboot?

reason for asking is i will like to reduce the downtime needed for the upgrade to just the reboot duration.

i notice when doing the ios-xe upgrade, i need to upload the image, run the command to install and the entire procedure must be perform all the same time.

"it is possible to set the prompt-level to none at the end of a install command and it does not ask you yes/no for any questions (normally at the end of the commit command of the upgrade, it asks you if you want to reload). If you set the prompt-level to none, the switch reloads as soon as it is ready to do so."

That option does exactly the opposite. We are searching for a way to install and commit the new version WITHOUT reloading the switch immediately. That way you could do all the preparatory work during production and when the maintenance window started you only need to reload the switch.

You are 100% correct. I must have typed this reply in the wrong thread. I was searching my no prompt and had about 3-4 tabs. Will fix.
