I want to upgrade the Cisco 9500 from 16.6.3 to 16.8.1 and after entering the command ( install activate file flash:16.8.1 it's showing
Field to activate, packages.conf.02- is the rollback file
packages.conf.02 did you manually move any packages.conf file ?
can you post dir output.
in general here is the steps for upgrade :
I would strongly recommend that you look at the latest 16.9.x release as this will have the same features as 16.8.1 and it is a long-lived release. 16.8.1 has already passed the End of Software Maintenance : https://www.cisco.com/c/en/us/products/collateral/routers/asr-1000-series-aggregation-services-routers/eos-eol-notice-c51-740983.html (yes that says routers, but this is the link you get to from the Catalyst 950o End of Sale page as well).
To get an understanding of the different timelines associated with the different IOS XE 16 release, see https://www.cisco.com/c/en/us/products/collateral/ios-nx-os-software/ios-xe-16/bulletin-c25-741178.html .
One you have chose your release, please follow the upgrade procedures outline in the Release Notes for that release.
