Hello All,
I plan on upgrading a couple of WS-C2960-24PC-L this weekend (*5 in total), to version 12.2(55)SE11, and noticed that these switches have a Software Upgrade option under the Maintenance Menu in the Web Browser version of Device Manager, and I have a couple of questions regarding this method...
1) Every IOS upgrade I've ever done was from the command line. Are there any benefits or drawbacks from upgrading the IOS from the Device Manager?
2) Does it automatically remove the old version when the upgrade begins/finishes? What if there's an issue with the new version and you need to fallback to the old/current version?
3) This is sort of related to #2. Is there a way to keep the old version on the switch and specify it in the config as sort of a "fallback version" in case the updated version won't boot for some reason?
*These switches are all located in remote locations away from where I am, so all will be upgraded via the Network and not Console cable, so was hoping there's a fallback method in case something goes wrong when the switch reboots...
One last thing... I checked around the forums but couldn't find a way to do this. Some people had scripts but their links were broken in their posts. I want to backup the current Images on these switches before I do the upgrade, and I am trying to copy the full directory where the image/bin file lives since its the version with the web-based Device Manager it has many files and directories...
Thanks in Advance,
Matt
