How to migrate the management platform

[maic]

The hardware of the server where the management platform is located is abnormal and needs to be taken down for maintenance. The management platform needs to be migrated to a new server. How can I ensure the normal operation of the service

this "should be straight forward"™, @maic .

• First add the new MS to the system,
• make sure it is functional,
• then stop the old one.
  It is only this simple if now other upgrades are to be done and only hardware is the issue. When java or mysql version are in play it becomes a little more complicated. Try to upgrade only one component at the time. (all hardware involved being a sinlge component).

Additional information: Cloudstack version is 4.18, OS system: Ubuntu 22. My cluster is deployed using local hard drive mode, and the secondary storage uses NFS. Both NFS and MySQL databases are deployed on server machines that need to be taken down for maintenance. NFS storage data and databases also need to be migrated to the new server for deployment. I have not found any specific operation documents. Can you help me? Thank you very much

how many KVM host - or is it single all-in-one-box?

[maic]

My cluster has a total of 105 hosts, of which 104 hosts have each created a KVM virtual machine; There are 5 KVM virtual machines on the host that are ready to be taken down for maintenance. The key virtual machines are all on this server, such as System VMs, Virtual routers, and critical business virtual machines
