Today I’m starting to upgrade my almost 40 Cisco Catalyst 3560G switches to a newer version of the IOS. Since these switches were installed over the course of about 2 years, a lot of them are running different IOS versions, so it’s time to get everything up to snuff and running the same version across the board. The latest version that’s installed on any of them is 12.2(25) SEE3 and according to Cisco support that version is now in deferral and it’s suggested to move to version 12.2(44) SE5. But…that version is also in deferral so the suggested is 12.2(44) SE6. Now at the time of this writing, the latest version is 12.2.50-SE. But I’m going to stick with version 12.2(44) SE6 for now as I’m not one to jump on the latest version of anything unless I absolutely have to.

You expedite the replacement, mount it in the rack, power her up, and then realize that you don’t have a copy of the most recent configuration or worse yet, you don’t have a copy at all!
