This is the Second Part of the Exchange Server 2007 Service Pack 1 Upgrade Series. in this article i will show you the upgrade process of Second Scenario of Exchange Server 2007 Deployments, which is “Cluster Continuous Replication – CCR“.

This is the First Article in this Article Series, which talks about Upgrading Typical Exchange Server 2007 to SP1:

Am using off course Microsoft Virtual Server 2005 R2 to run my 5 Virtual Servers. these are the servers I am running on my Lab:

  • PRODC01: This is my and Only Domain Controller which hosts my Single Domain Model which is called “ProRangers.net

  • PRO-HC1: This is Exchange Server 2007 HUB and CAS Server Roles and also my File Share Witness Server (FSW Server).
  • PRO-CCR1: This is the First Cluster Continuous Replication Node – First CCR node or in other words, the Active Node.
  • PRO-CCR2: Last Server which is the Second Cluster Continuous Replication Node – Second CCR node or in other words, the Passive Node.
  • PROMAIL: this is my Clustered Mailbox Server Cluster Group Name.

Exchange 2007 Service Pack 1 Software Requirements

As I mentioned on the First Part of this Article Series, Exchange 2007 SP1 requires the following Software updates and hotfixes to be deployed under all your Exchange Server 2007 RTM Versions. its recommended to deploy these requirements before the actual upgrade process of SP1. These Requirements are:

For Production Exchange Environment (running 64-Bit Version):

For Testing Exchange Environment (running 32-Bit Version):

in my lab, I installed the above requirements before I started the actual upgrade process of SP1.

Which Server needs to be upgraded first ? and what is the recommended upgrade process for Exchange 2007 ?

the Recommended Upgrade sequence for your Exchange 2007 Environment based on your Server Roles, is to start with Client Access Servers – CAS which is the Internet Facing Server and to leave any Mailbox Server Role till the end of the Upgrade process. Start upgrading the First CAS Server , then continue with other CAS Servers under same AD Site or other AD Sites. here is the recommended Upgrade Path based on Exchange Server Roles:

1. Client Access servers
2. Unified Messaging servers
3. Hub Transport servers
4. Edge Transport servers
5. Mailbox servers

Microsoft Says “If you upgrade your servers in this order, you may avoid potential service interruptions”

Important Points to consider for upgrade process for Clustered Mailbox Server in CCR Environment

There are specific things that must be considered and planned for with respect to upgrading a clustered mailbox server in CCR environment to Service Pack 1:

  • before you can upgrade to Exchange Server 2007 SP1 , the Clustered Nodes must be running Windows Server 2003 SP2.
  • a clustered mailbox server can be upgrade to Exchange Server 2007 Service Pack 1 ONLY by using the Command-Line Version of Setup (Setup.com /UpgradeCMS), you can’t use the graphical user interface version of setup to upgrade an existing Clustered Mailbox Server running RTM Version of Exchange 2007 to service pack 1 Version of Exchange 2007.
  • backup your clustered mailbox server prior to upgrading to Exchange Server 2007 Service Pack 1 and also after successfully completing the upgrade service pack 1.
  • update the operating system for all your Servers running the RTM Version of Exchange Server 2007 that mentioned above before you start the upgrade process to SP1. the upgrade process will not start if the above update (KB933360) was not installed on all your Exchange Servers 2007.
  • upgrading clustered mailbox server in CCR environment to Service Pack 1 results in outage for the email service during the upgrade process.
  • Both Nodes need to be upgraded to Service Pack 1 in order to be supported, but you must upgrade each node one at a time, then after each node has been upgraded to Service Pack 1, then the Clustered Mailbox Server is upgraded and then brought online.
  • move all clustered resource groups to the active node which includes the clustered mailbox server – CMS, then start with Passive Node, don’t start with Active Node. (In my lab, i will start with PRO-CCR2).

Upgrade Passive Node (PRO-CCR2) of Clustered Mailbox Server in CCR Environment

now, we can start the upgrade process of Clustered Mailbox Server in a CCR Environment, we will start with the Passive Node First, so here are the steps:

  1. Logon to the Passive Node (PRO-CCR2) that has delegated the Exchange Server Administrators Role and is part of Local Administrator of on the Passive Node. for my lab i use the Domain Administrator Account. remember that we don’t require a user that has been delegated the “Exchange Organization Administrators”, such user account is only required when you upgrade your First Exchange Server 2007 RTM Server under your Forest, cause it needs a permission on the AD Schema and Exchange Organization Containers and Folders under the schema, since I had a Hub and CAS server already installed under this organization, i used such account to upgrade this first Hub and CAS server. after the successful installation of my first Exchange 2007 RMT Server to SP1 , then the rest of the upgrade process i only require a user which has been delegated the “Exchange Server Administrators” Role.
  2. Move all Clustered Resources Groups to the Active Node (PRO-CCR1). make sure that the passive node hosts NO Cluster Resources, all Clustered Resources and Groups need to be moved to the Active Node. Clustered Mailbox Server Cluster Group can be left with Online Status at the Active CCR Node during the upgrade process on the passive node. you can use this command from the command line of the passive Node to move your clustered resources from passive node to active node: cluster group <Cluster_Group_Name> /Move
  3. Start the Windows Firewall/Internet Connection Sharing (ICS) service. This service is disabled by default, and you must set its Startup type to Manual or Automatic for the service to be started, starting this service is necessary to allow SP1 Setup to add Windows Firewall exceptions for Exchange services. After the clustered mailbox server has been upgraded on passive node, you can stop and disable this service. here i used the manual status.SP1 on Active CCR Node # 1 

  4. Stop any Performance Counters services, like Performance Logs and Alerts and any Microsoft Operations Manager agents.
  5. Stop, and then restart the Remote Registry service on the passive node.SP1 on Active CCR Node # 2 

  6. Open a Command Prompt window, and then navigate to the Exchange 2007 SP1 installation files, then run the following command:D:\Setup.com /m:upgrade

    where D: Drive is my DVD Media
     

    SP1 on Passive CCR Node # 3

    SP1 on Passive CCR Node # 4

    SP1 on Passive CCR Node # 5

  7. Now, after we successfully upgraded the Passive Node (PRO-CCR2) , we have to restart the passive node, this is a must. Now, in my lab, i faced an issue from leaving the Windows Firewall Service in the starting state, and i lost communication between the Two Nodes, so since i don’t use Windows Firewall in my lab, and since i am not enabling the Fire Wall service between the Clustered Node, i sat it again as disabled, and restarted the passive node again, and everything was working fine. If you faced the same issue in your production environment, and you are not enabling the communication between the two Clustered Nodes through Windows Firewall, just disable it back again as it was before the upgrade, and restart your passive node again.

Upgrade Clustered Mailbox Server – CMS (or in my lab PROMAIL) in CCR Environment

now, after successfully we upgraded the Passive Node of the Clustered Mailbox Server in the CCR Environment, the next step would be to upgrade the Clustered Mailbox Server Clustered Group – CMS , where i called it here in my lab as (PROMAIL). in this step we will upgrade the CMS from the passive node, and while the CMS Group is in Offline State, its important to bring the CMS Group or PROMAIL (as I call it in my lab) offline before you upgrade it to SP1. here are the steps you need to do:

  1. after you logged into Passive Node (PRO-CCR2), open Exchange Management Shell (EMS) of Exchange Server 2007, and bring the Clustered Mailbox Server “CMS” – PROMAIL offline. you have to know that by starting this process, your Mail Service will be down, so the users will not be able to connect to their mailboxes till you successfully complete CMS Upgrade process to Service Pack 1. To bring the CMS Cluster Group (PROMAIL) offline, run the following command from EMS:Stop-ClusteredMailboxServer PROMAIL -StopReason “<Type Any Descriptive Reasons like : Upgrading CMS to E2K7SP1>”

    SP1 on Passive CCR Node # 6 

    from the above screen, to can see that the command asks for Confirmation for the action that is going to be applied to your CMS Cluster Group, so click “Y” to proceed. if you want to provide this confirmation within the “Stop-ClsuterMailboxServer” command, then this is the full command:

    Stop-ClusteredMailboxServer PROMAIL -StopReason “<Type Any Descriptive Reasons like : Upgrading CMS to E2K7SP1>” -Confirm:$False

  2. now, you need to move the Clustered Mailbox Server – CMS “PROMAIL” from CCR Active Node (which is not yet upgraded to SP1) to CCR Passive Node (which was upgraded successfully to SP1) by running the following command from Passive Node (PRO-CCR2):M ove-ClusteredMailboxServer PROMAIL -TargetMachine PRO-CCR2 -MoveComment “<use your own comments here>”  

    SP1 on Passive CCR Node # 8

    also, to append the confirmation for this command along with your command, here is the full command:

    Move-ClusteredMailboxServer PROMAIL -TargetMachine PRO-CCR2 -MoveComment “<use your own comments here>” -Confirm:$False

  3. Now, after we move the Clustered Mailbox Server “CMS” – PROMAIL from Active CCR Node (PRO-CCR1) to Passive CCR Node (PRO-CCR2), we need to upgrade the Clustered Mailbox Server – CMS – Cluster Group to Service Pack 1 Version. browse to Exchange Server 2007 Service Pack 1 Setup Files , and run the following command from the command line:D:\Setup.com /UpgradeCMS  

    UpgradeCMS

    UpgradeCMS #2

    UpgradeCMS # 3

    After successfully upgrading the Clustered Mailbox Server – CMS (PROMAIL) to Service Pack 1 Version, the Setup brings this Cluster Group Online again, and your users can access their mailboxes again. when you reach this stage, actually your Exchange Service provided by Exchange Server 2007 will be running Service Pack 1 Version of Exchange Server 2007 with full features provided by SP1, the only remaining step is to upgrade your First (Active CCR Node – PRO-CCR1). which will be demonstrated in the following section.

Upgrade Active Node (PRO-CCR1) of Clustered Mailbox Server in CCR Environment

now, we can start the upgrade process of the first CCR Node (PRO-CCR1) in the CCR Environment:

  1. Logon to the First Node (PRO-CCR1) that has delegated the Exchange Server Administrators Role and is part of Local Administrator of on the First Node.
  2. Move all Clustered Resources Groups to the Second Node (PRO-CCR2). make sure that the First Node (PR-CCR1) hosts NO Cluster Resources, all Clustered Resources and Groups must be moved to the Second CCR Node which was successfully upgraded to SP1 and which runs the CMS Cluster Group. Clustered Mailbox Server Cluster Group can be left with Online Status at the Second CCR Node during the upgrade process on the First CCR Node. you can use this command from the command line of the First Node to move your clustered resources from first node to second node:cluster group <Cluster_Group_Name> /Move
     

  3. Start the Windows Firewall/Internet Connection Sharing (ICS) service on the First CCR Node.SP1 on Active CCR Node # 1 

  4. Stop any Performance Counters services, like Performance Logs and Alerts and any Microsoft Operations Manager agents.
  5. Stop, and then restart the Remote Registry service on the First Node.SP1 on Active CCR Node # 2 

  6. Open a Command Prompt window, and then navigate to the Exchange 2007 SP1 installation files, then run the following command:D:\Setup.com /m:upgrade

    where D: Drive is my DVD Media
     

    SP1 on Active CCR Node # 4

  7. After successfully upgrading the First CCR Node, you need to restart the CCR Node first, and don’t forget to disable back the Windows Firewall Service before the restart.
  8. after you upgraded all your Exchange 2007 Servers from RTM to Service Pack 1 Edition, open Exchange Management Console, and make sure that all your Exchange Servers have the same Version Edition.Exchagne Version after SP1
