Hi,
Have a customer with a multi-controller environment and we need to do an upgrade in response to a couple of bugs that we uncovered.
The customer is very nervous about the whole thing and wants to upgrade only one site and let it run independantly for some time to test and make sure everything is ok, before doing the rest.
We have control-plane-security enabled and I was wondering if there are any adverse affects of reconnecting that local to the master a few days later after we upgrade the rest?
Unfortunately, it's looking like they will want each local site to be done on different days.
So if a local is disconnected from it's master for an extended period, what other implications are there?
Thanks
