Its been 10 months since the Exchange team released the SP1 for Microsoft Exchange server 2010. When this release happened,
lot of bugs came up, which the Exchange team try to fix it. As mentioned in
Prem's previous blog, i was waiting for the platform to get stabilized.
Thanks to the Exchange server team, who keeps updating the hotfixes and OS bugs. Since the release of Windows server 2008 R2-SP1, most of the issues were settled... and now its my time to start our production server to bring it to the latest
platform. This is the most stabilized platform so far.
Let get started.
Current mail server platform : Microsoft Exchange server 2010 – Rollup 5
Our server structure:
CAUTION : AFTER YOU UPGRADE TO EXCHANGE SERVER 2010 SP1, YOU CAN’T UNINSTALL THE SERVICE PACK TO REVERT TO EXCHANGE 2010 RTM (Released to Manufacturer). If you uninstall Exchange 2010 SP1, you remove Exchange server from the domain!!!
You have to start to upgrade your Exchange 2010 server role in the following manner:
NOTE : If your organization uses a load balanced CAS server, you must upgrade all the CAS in that array to Exchange 2010 SP1 one by one and then move to the next role based server.
Stop the following service from this server and run this command again:
Copy the DVD image to the local drive and run the setup.
Choose the Exchange language option for upgrade – Select from DVD Source and select “English”.
Now click “Install Microsoft Exchange Server upgrade”.
Accept the license agreement and click Next.
Readiness Checks starts….
Make sure that you stop the backup agent service to be stopped..or else you will get this below error
and then install the others if required…then again re-run the setup once the readiness check is completed, go for upgrade.
This will take minimum 30 to 40 minutes, depends on the performance of the system….
One server finish…upgradation…not over yet!!! Right now i can tell you that the mail flow is smooth…because of the load balancing on the H&C Servers.
Same step you have to do on the next HUB & CAS server in this array…!!!
Next one finishes in 30 minutes..HUB & CAS Server upgraded to SP1….

Targeting Mail Box server…Same step as before…but here you have to be a bit cautious cause its an upgrade to DAG group member
When upgrading a database availability group (DAG) member to Exchange 2010 SP1, you need to consider and plan for some specific issues. Before upgrading any DAG members to Exchange 2010 SP1, consider the following. More information to the below,
Get-DatabaseAvailabilityGroup <DAGName> -Status | Format-List PrimaryActiveManager
Make sure that you start with the passive DAG node of the mailbox server
One finish…now the real task..you have to change the active one to passive (Passive is now with Exchange server 2010 SP1).

To do the 2nd mailbox installation..make this as passive…From the Power Shell command
