We have two hosts, one locally and the other remote, and require a second vCenter for the remote location. We are doing this for Business Continuity and will be replicating our VMs between the two sites. Our current local vCenter runs vCenter Server 5.1 Essentials. When I go to the Download page, I see several options for downloads including VMware vCenter Server 5.5.0b and modules, VMware vCenter Server 5.5.0b Appliance, OVF file, System Disk, Data Disk, and Appliance. Which one should I download? Also, our current vCenter is running 5.1 and these downloads are all for 5.5. Will the different versions cause us concern?
Thanks,
Dave
