I'm curious what the recommended best practice is for migrating a production environment with replication from 0.7 to 0.8 given the protocol upgrade. Some specific questions I have are:
a) Is it possible to mix 0.7 and 0.8 servers for a given partition during the migration? b) If we can't mix server versions, how do we do a zero-downtime upgrade? c) Will 0.7 clients continue to communicate correctly on-the-wire with the 0.8 server until they can be upgraded? Any war stories of production upgrades would be helpful. Thanks in advance. - Clark
