回撤流程可能包括从集群移除或挂起队列管理器、向后迁移和在外部问题得到解决之前保持队列管理器离线。

The procedure could involve removing or suspending the queue manager from the cluster, backwards migrating, or keeping the queue manager offline until an external issue is resolved.

迁移不过就是永不退回的故障转移，扩展是永远不将主节点置于离线的故障转移。

Migration is simply a failover that never fails back, and scaling up is a failover in which the primary node never goes offline.

如果允许服务离线一段时间，那么迁移将更容易。

It's much easier if you can take the service offline for a period of time.
