HI Friend, Its doable with no any issues. Please follow below steps. 1. Build a new vCenter (Your first step is correct) 2. Create a cluster (as this is new vCenter there will not be any host already available. Hence cluster creation wizard will not get host to be added into new cluster). So initially empty cluster would be created. 3. Once the cluster is created, straightway right click on cluster and add your all hosts one by one. No need to unregister and VM. VMs will be automatically added which were there on datastore available with all hosts. Remember, 1. we do not mount any datastore on vCenter, we mount datastore on host. 2. If you mount new datastore (which was not there earlier), you can mount once new hosts are added to new cluster. (Your SAN admin would help you out) 3. If you want to move your VMs from earlier datastore to newly added/mounted datastore, please SVMotion these VMs (by right clicking on VM >>migrate>>to datastore>>select datastore which is new)..Plz follow the same process for all the VMs. 4. You no need to add empty hosts to the new cluster, just straightway add all the hosts without registering VMs. Later you can migrate to other datastore as per requirement. NO need to upload or download any VM. 5. Please make sure your ESXi hosts are going to be compatible with new vCenter. Old version of ESXi always compatible with new version of vCenter. Just check if you have all valid licenses. Please let me know if you need any clarification
