红帽全球峰会2.8. 备份重要数据和查看服务器状态
在迁移应用之前，您需要了解以下潜在问题：
-
迁移可能会删除临时文件夹。在迁移之前，存储在
data/content/目录中的所有部署都必须备份，并在迁移完成后进行恢复。否则，由于缺少内容，服务器将无法启动。 -
在迁移之前，请处理任何开放事务并删除
data/tx-object-store/transaction 目录。 -
必须检查
data/timer-service-data中的持久定时器数据，以确定升级后是否仍然适用。在升级前，请查看该目录中的deployment-*文件以确定哪些计时器仍在使用。
务必在开始之前备份当前服务器配置和应用程序。
