We are evaluating options to bring our devices that are all in a Full stack template to the latest stable firmware with hundreds of networks.
Since we are using template this means when an upgrade is applied to the template all devices atatched to it are going to be upgraded in one hit. If there is an uncaught test case then we potentialy has many sites that we have to deal with at the same time.
How do we best stage rollout so that only a subset of sites in the template network are upgraded at any one time to minimise any impacts?
I can't see any option here. Removing devices from the template is not a viable option here.
We have over 2K networks and yes we are using templates on most of the sites. We always test the firmware in a lab , then we do a pilot with a couple sites that are unbound from the template , then we do a massive rollout
