I spotted this in the release notes, but am unsure how to now actual do this. I have two machines running carp, as a failover pair, and I normally upgrade BACKUP, reboot, switch to MASTER, and do the other and flip back. But I dont quite see how to do this from 13 to 14 - my worry is that when the upgraded machine comes back up, it will just take on MASTER and I will have two MASTERs. I see that it's possible to make the talk the old protocol, but then how do I move to the new protocol ? thanks, -pete.
