We are in the process of relocating from our existing DC to a new DC. I wish to know whether it would be possible for the network and server resources in both the existing DC and New DC to work in parallel till the resources in the New DC is considered to be stable, thus enabling a zero downtime for the business. If yes, are there any documents which I can refer to make the corresponding plans. I am more concerned in the data flow for the network(swithing and routing)to acheive the above mentioned goals.
I have this problem too.
