IOS XR ASR 9901 upgrade

[Mostafa Alzareef]

I currently have an ASR 9901 running IOS XR version 7.9.1, and I'm planning to upgrade to version 24.2.2 using a USB drive. My goal is to keep the existing configurations on the router intact during the upgrade.
could you send me the steps
what image i should use in below photo

Additionally, I've installed a feature package compatible with version 7.9.1. Once I upgrade to 24.2.2, will I need to install a new feature package that's compatible with the new version, or will the existing one still work?

Thanks in advance for your help!

In order to upgrade you must upgrade every active package on the box, for example if you have mini, mpls, bgp, then you must upgrade all of those at the same time. You can add additional packages or SMUs as well but that would be the minimum packages required. Do NOT put the usb tar file on the USB drive, that is for reimage, download the iso and optional packages like you normally would and put them on USB, when the USB is in the router it will be disk2: or usb:, you can use show media to see how it shows up, then use install add source disk2: ..., then activate, and commit after reload.

Thanks,
