We need to migrate a large application from one datacenter (NJ) to another datacenter (CA).

The easiest way for us to get the databases and filesystems would be for us to create a clone of all the appropriate luns onto a raid group and simply ship the disks to the new datacenter. Due to the size, we don't want to use ethernet or external USB storage. It's about 2.5Tb in size.

Question is, we use CX4-120 arrays, how is it possible to move a raid group physically between arrays?

Can I create a raidgroup and luns on a set of disks, then swap-out the disks with the new ones? Im assuming here that the layout is exactly matched. I was worried that the array would see the different serial numbers and reject or fault.

Im looking for options going from one CX to another CX. Would multiple single-disks work better than a raid group?

Im assuming the RG/LUN config is saved in the array/vault and not on the drives, but I don't really know how that works specifically.

Are there other options?
