If a user downgrades to PV0, the user must wait until all nodes have replicated past the first PV0 write before upgrading back to PV0. This applies to all versions since PV1 was introduced in 3.2. |

jeffrey.allen This writing ticket is related to the discussion on that ticket, but is not related to the ticket itself. This is making users aware of what they must do to avoid a potential problem that has existed in replication protocol downgrade, then upgrade since 3.2. See this comment and the comment above it for details. |
