Upgrading Catalyst switches

[martacarl90]

i was wondering what methods people use to upgrade alot of switches at the same time, if you dont have dna license?

i have tried to make some jobs via cattools for diffrente model switches, but its a pain with c9200 but works fine with 9300.

so i am looking for a Smarter method.

what are you guys using? ansible? or something else .

pros and cons?

Generally I'd like to perform it manually, since it's just copy the image and issuing the upgrade command.

But if you have that many switches, I would say Python with Netmiko and Getpass for sure can help, you can build pretty much any sequence of commands and validations to automate as much you like.

   - @martacarl90             I don't recommend upgrading switches at the same time, it does not mean that a tool
                                        could be useful to schedule upgrades in cascade, the reason being that it's important
                                        to keep track if upgrades are successful per device; for instance if the first one fails
                                        it's important that you can stop the train
