Howto Move HyperFlex Cluster to New vCenter

It’s possible that you installed the HyperFlex cluster and register it to a vCenter server and now you want to move it to another vCenter server. There are serveral reasons to do this. During the installation of HyperFlex, everything is done by the installer. Hosts were added, plugin was loaded. But how can you easily do it and what steps like installing plugins etc should you do on the new vCenter server.

Old vCenter Server

Right now the HX cluster is registered to the .27 vCenter server and it’s online without any warnings.

It’s the HyperFlex Edge cluster, which got 3 servers.

 

Move to new vCenter Server

When you installed the new vCenter server, everything is empty.

To make the move of the HX cluster, you should open a SSH connection to the HX Cluster. This can be done via https://<cluster ip address>/mssh

We’re using the command where –vcenter-cluster is the name of the cluster in vCenter and –vcenter-datacenter is the name of the datacenter.

stcli cluster reregister --vcenter-cluster HXEdge --vcenter-datacenter HXAMSCCC --vcenter-password 'S#cret' --vcenter-url 10.61.124.60 --vcenter-user administrator@vsphere.local

 

 

Right now you see that the reregister is failing. This is because I didnt’ create the DC and Cluster in vCenter.

Now the DC and Cluster are created. What you will have to do is to add manually the hosts to the cluster.

Do this for all the servers.

 

Just run the command again and you will get :

You can verify if the cluster is registered to the new vCenter with :

If you go to the vCenter you will see at the global inventory a new tab of HyperFlex. So there is no need to install any plugin. Easy isn’t !

 

After a few minutes everything is alright at the HX Connect.

 

If you see the warning :
