In the last days i read about Cisco IOS XE 17.9.x End-of-Sale and End-of-Life announcement by Cisco (https://www.cisco.com/c/en/us/products/collateral/ios-nx-os-software/ios-xe-17/ios-xe-17-9-x-eol.html) so i decide to take advantage of this bulletin to upgrade the switch in my SD-Access lab using the SWIM (Software Image Management) feature.
First of all i need to sync my Catalyst Center (version 2.3.5.5) to Cisco image repository in order to download the latest image catalog:
After that i need to choose the Family product i want to upgrade and mark as “Golden” the image version that i want to run in my devices:
During this activity you can also download some specific SMU (Software Maintenance Upgrade) for the main image version:
Once the image download has finished i can proceed with the switch upgrade. In this case i want to upgrade 4 switches located in 3 different sites starting from IOS XE 17.9.5 version:
The SWIM process starts and let you decide how to proceed with the upgrade (e.g. ISSU or Disruptive, what kind of Pre-upgrade and Post-upgrade checks to do, Activate or not the new image into the switches and so on):
After you complete the SWIM process, the upgrade starts:
You can also see all the upgrade details clicking the “See Details” blue link:
When the whole process is over you can check that all the operation complete and the overall upgrade is finish:
