Would changing workflows corrupt previous cases?

Right now when we modify workflows we dump and load, which also clears out the cases. Obviously in production we wouldn't want to do that. Eventually we'll even have a UI for modifying workflows. But if we, say, add a state to the end of the workflow, would that corrupt existing cases? What about modifying a state/action?

Just something to think about

首先跟踪当前的 workflow dump/load 操作，以及它如何清除现有 cases。检查添加 state 或修改 state/action 对已存储 cases 的影响；完成意味着这些 workflow 更改的兼容性行为已定义并验证。
