温馨提示
※ 如果源端“抓取”进程不需要合并的话源端不用做任何改动（如果想合并的话可以使用eventactions(stop)命令实现多个进程在同一点处停止）
※ 如果源端“投递”进程不需要合并的话源端不用做任何改动（如果想合并的话可以使用eventactions(stop)命令实现多个进程在同一点处停止）
※ 如果目标端“复制”进程不需要合并的话直接执行STOP命令即可，如果想合并的话可以使用eventactions(ignore,stop)命令实现多个进程在同一点处停止，从而干净的将多个replicate进程合并到一个新coordinated进程中
※ 原来的trail文件可以继续使用，转coordinated模式不涉及trail格式的更改
※ 目标端需要重新配置replicat进程，配置前需要停止旧的传统模式的replicat进程实验开始
