System Center – Virtual Machine Manager (VMM) Is there for a long time, many used this as the primary tool for managing the virtual and physical environment, but now days Cloud is playing more and more a big role in the infrastructure, Tools are also switching with Azure Arc or with Windows Admin center you have some powerfull tools that can mange the infrastructure.
Hybrid management with Azure
Efficiently managing IT resources that are sprawled across various locations without slowing down developer innovation is a key challenge that IT leaders face today. Azure Arc enables you to seamlessly govern, manage, and secure Windows and Linux servers, Kubernetes clusters, and applications across on-premises, multiple clouds, and the edge from a single control plane.
I must say I see less and less Vmware and VMM as I move them all to Azure. but in the meantime many of you will still using this so here is a little guide on how to upgrade from VMM 2019 to VMM 2022.
Get started with System Center 2022
- Get started at the Evaluation Center, or get it directly from the Volume Licensing Service Center.
- Learn more by going to:
Make sure the following steps are taken, else you will see some errors, I tried to simulate that so that you can see the expected error message.
- Complete any jobs that are currently running in VMM. note that the jobs history is deleted during the upgrade.
- Close any connections to the VMM management server, including the VMM console and the VMM command shell.
- Close any other programs that are running on the VMM management server.
- Ensure that there are no pending restarts on VMM servers.
- Perform a full backup of the VMM database.
- If the current SQL Server database used Always On availability groups:
- If the VMM database is included in the availability group, remove it in SQL Server Management Studio.
- Initiate a failover to the computer that is running SQL Server, on which the VMM database is installed.
- If you’re running Operations Manager with VMM, disconnect the connection between VMM and Operations Manager server.
Uninstall the System Center VMM
- Go to Control Panel > Programs > Program and Features, select Virtual Machine Manager and click Uninstall.
- On the Uninstall wizard, select Remove Features, select both VMM management Server and VMM Console under the features to remove.
- On database options page, select Retain database.
- Review the summary and click Uninstall.
Remember if you have multiple consoles you need to upgrade these also.
Now that VMM is uninstalled we can proceed. Make sure the check box is checked RETAIN Database
Now we can start the setup again.
We do a full install Console and Management server.
As my VMM server was based on windows server 2016 see the netbios name, I upgraded the server to Windows server 2022 and with the SQL server 2019.
When selecting the Database make sure you use the correct name, If you don’t know the name you can see the name in de SQL server, the wrong Database name gives you the above error.
With the correct Database name.
The next step is upgrade the Database and install VMM
make sure you use the same library name as before.
make sure you take the upgrade steps that are needed in the article when needed.
Now that the VMM server is up and running we can use VMM again and the Database and the configuration is as before.
