Hello all,
In terms of doing IOS-XE software upgrades, there are 2 ways to do it - the install mode way, or the request platform way. @Leo Laohoo has written some great guides for upgrading ISR models with request platform and upgrading Cat 9k models with install mode (See attached file).
The bummer about install mode is that it's very difficult to schedule a reboot, it's kind of an all-or-nothing thing. With the request platform method however, you can unpack the files beforehand, and then run a simple reload command when you're ready to upgrade.
My question is, can you use the request platform method on any device running IOS-XE ? If so, wouldn't that be the preferred method since it's so easy to schedule your reboots? Why would anyone use the install mode?
