I have a datacenter running ESXi 5.1 and plan to build a second one. The second site has its own VMs but also being used as a DR site if site one is completely down for a long time. Since ESXi 5.5 is available, should I build site 2 with this release and upgrade site 1 to 5.5 later to keep both sites running the same version?
I usually don't jump on the new release right away but since site 2 is a remote location, I want to install the latest version so I don't have to make another trip. Hardware is two Dell R620 servers.
If you have both 5.1 and 5.5 installed in your environment, I would like to get you advices. Should I stay with 5.1 version or go ahead with 5.5 since it's a stable version at this time?
Thanks,
H Doan
