Thanks Anthony, good advice all around (especially the beer). And yes, I read the OS Admin Guide. Very helpful. Although the OS Guide talks about using the web UI to switch versions, while the release notes make a point to suggest you do switch version via the CLI. I wonder if something changed? Either way I'm fine with the CLI.
It's my opinion that the CLI is superior to the web UI. So, even if Cisco hadn't mentioned their preference, I would have used the CLI anyway. Either will work. I know plenty of Cisco engineers who don't use the CLI at all, and perform every upgrade and switch version through the Web UI just fine.
