Thanks Colin. A/B Fabrics, multiple switches per fabric. I'm looking for something a little more in depth relating to the "migrate configs" step you mention. Hoping someone else out there has completed such a migration, with configs including vsans/ivrs/port-channels/ persistent and non-persistent FCID's, that can share some gotchas and best practices. It would be nice if it were just backup/restore config over to new hardware, however I don't believe that'll be the case.

G'day,

It will depend greatly on how your SAN is configured to begin with... What type of zoning, iscsi, fcip, vsans's etc.

If you are zoning by pwwn it "should" be pretty smooth to plug in from one switch to another slowly moving host by host over.

I've done if before via changing data centre from one floor to another which meant moving the hosts but not the arrays until the very last outage.

It was a very lengthy process but very successful :-)
