概述

升级主要分为mailbox server和cas server，其中mailbox server即DAG members，升级过程中参考了以下官方文档：
Anti-Virus Software in the Operating System on Exchange Servers
Exchange admin center in Exchange 2013
Managing database availability groups

本次升级了解到了以下几点实践经验：

  • 建议exchange所有节点之间端口全开
  • 建议打开ipv6（经观察节点之间的心跳联系会以ipv6地址进行）
  • 升级Cu补丁时，建议cd到所在目录以./<patch_name>运行，而非直接双击运行

  • exchange 2013环境中，只有cas角色才能访问owa和ecp，即https://<CasServerName>/owa和https://<CasServerName>/ecp

  • 对于exchange server上安装的杀毒软件，需要对exchange安装目录和db所在的目录添加例外。按照官方文档，还需要对exchange进程添加例外，但是进程工作时需要访问的文件已经被添加，所以进程级别没有做了。

下面开始升级步骤。

mailbox server升级步骤

  1. 传输队列状态设置为drainSet-ServerComponentState <ServerName> -Component HubTransport -State Draining -Requester Maintenance

  2. 传输队列开始drainRestart-Service MSExchangeTransport

  3. 将server服务切换到dag内其他服务器Redirect-Message-Server <ServerName1> -Target <ServerName2>

  4. 暂停该节点Suspend-ClusterNode -Name <ServerName>

  5. 把该台server上的active db迁移到其他server上Set-MailboxServer <ServerName> -DatabaseCopyActivationDisabledAndMoveNow $True

  6. 避免在该台server上自动active dbSet-MailboxServer <ServerName> -DatabaseCopyAutoActivationPolicy Blocked

  7. 把服务器置为维护模式Set-ServerComponentState <ServerName> -Component ServerWideOffline -State Inactive -Requester Maintenance

  8. 安装CuSetup.exe /m:upgrade /IAcceptExchangeServerLicenseTerms

附上验证server已处于维护模式命令：
To verify the server has been placed into maintenance mode, run Get-ServerComponentState <ServerName> | ft Component,State -Autosize
To verify the server is not hosting any active database copies, run Get-MailboxServer <ServerName> | ft DatabaseCopy* -Autosize
To verify that the node is paused, run Get-ClusterNode <ServerName> | fl
To verify that all transport queues have been drained, run Get-Queue

mailbox server升级后恢复服务步骤

  1. ServerWideOffline组件恢复Set-ServerComponentState <ServerName> -Component ServerWideOffline -State Active -Requester Maintenance

  2. 集群内恢复 Resume-ClusterNode <ServerName>

  3. server上可以active dbSet-MailboxServer <ServerName> -DatabaseCopyActivationDisabledAndMoveNow $False

  4. server上可以active dbSet-MailboxServer <ServerName> -DatabaseCopyAutoActivationPolicy Unrestricted

  5. 传输服务开启Set-ServerComponentState <ServerName> -Component HubTransport -State Active -Requester Maintenance

  6. 重启传输服务Restart-Service MSExchangeTransport

cas server升级以及服务恢复步骤

再此不赘述，区别在于运行Cu之前在windows nlb内block掉server ip（具体情况视架构而定）
