Can anyone please explain if a GCS level protocol bumped will have an effect on rolling upgrades.

Does this mean in a three node cluster:

Once the first node is upgrade and its on the new protocol version it will not be able to communicate with the remaining nodes until they have also been upgraded?
This would be a huge problem.
