I was reading through the 17.15.5 release notes and spotted this:

Switch Templates with bound networks cannot directly upgrade from CS firmware to IOS XE firmware. Cisco recommends unbinding the network, upgrading it, then rebinding it to an IOS XE template.

That seems fine if you've got a handful of sites, but we've got hundreds of template networks. Unbinding and rebinding every single one cannot surely be the recommended approach here?

Just wondering what everyone else has done.

• Did you really have to unbind every network?
• Is there a better way that isn't mentioned in the docs?
• Did TAC or your Meraki SE have another approach?
• Has anyone scripted the whole thing with the API?

Feels like this can't be the intended process for larger deployments, so I'm interested to hear how others have handled it.

If unbinding really is the only way - what are the impacts here? Are any settings or configuration lost/defaulted during the unbinding and re-binding process?
