We currently have 3 ESX servers and Virtual centre with a fibre San attached. We have decided to move to another Datacentre and migrate all of our equipment. We will be using temporary hardware to host temporary virtual machines whilst we move the SAN to the new location as our services need to be up 24hrs. Has anyone done something like this before, i'm unsure if to use a new internal network range at the new DC but then this would mean we would have to re-ip all of the current setup to the new range, which I think this would be a big job. Is it easy to re-ip a whole San setup with 3 x esx servers and VC etc?
