I am wondering if anyone has gone through an upgrade from an older to a newer model of the Adaptec 3Gb/s SAS RAID card. For example, Adaptec 3805 to 5805. And of course, I'm looking for a drop-in-replacement upgrade approach rather than re-creating arrays and migrating any data back. I've sent a support request to Adaptec and they're saying it is compatible. I'd like to know if anyone has ever done an upgrade such as one like this?
