Hello,
I need to install windows security update(not CU) on Exchange 2013 DAG.
Is this correct procedure
https://www.aventistech.com/kb/how-to-perform-windows-update-for-exchange-2013-dag-cluster/
https://enterpriseit.co/microsoft-exchange/install-windows-updates-dag-members/
My environment
Server1 (client access)- ex 2013
Server2 (client access,mailbox) DAG member- ex 2013
Server3 (client access,mailbox) DAG member- ex 2013
Any advice for me?
Thank you
Yes, those will all work.
With Windows Updates, all you really need to do is move the active databases to other servers, and mark the server down in any load balancer that you may be using that clients connect to.
Once you apply the updates, reboot, enable the server in the load balancer if you are using that and you are back in business
Hi @fsdg ,
I agree with Andy, you could do the update follow the procedures of these articles.
To update the DAG members with new patches, the update process should be managed to prevent all of the DAG members from being offline at the same time. So you need to run the Move-ActiveMailboxDatabase -Server “ExchangeServerYouAreUpdating” cmdlet to perform server switchover to prevent activity on the server you are going to install updates. Perform a Server Switchover
And after the update and verify, run the same cmdlet on the second server then reboot, check the state and update.
In addition, this article Performing maintenance on DAG members has a detailed description for maintenance methods, and Installing updates on DAG members provides the steps to install updates on DAG members.
