Re: Transfer VMs across DataCenters

Well, there isn't any specific guide so far. To transfer VMs from one datacenter to another, just make the target server available to the source server via SSH, exchange keys and transfer the VMs, that's all there is to it.

You should take into account that as latency increases, the effective bandwidths will be reduced as an effect of the very TCP protocol nature and small TCP windows. Nonetheless, you should still keep a viable bandwidth, even for big vms, when latency keeps below 30-40 ms.

Of course, once you have completed the first transfer, (c)VMWare's CBT technology will take care to minimize the data transferred as only changed blocks will be sent.
