We are upgrading our SAN from an AX150 to an HP MSA2212C. The current SAN stores our e-store data -- orders, shipping, and so forth. I know there will be at least a brief outage when we cut over the old SAN to the new one.
I've never done a SAN migration before. It seems as though it should be as simple as installing the new SAN, bringing it online, and copying data from one SAN to the other. I'm guessing that's not the case, however.
What are the best ways to copy the data from the old SAN to the new SAN, and then bring the new SAN online? I want to minimize system downtime.
