I've got a f230 with 4 shelves of 4GB disks and its replacement, an f740. I talked to netapp support and they recommended that the best method to move the data from the f230 to the f740 would be to tapes with dump and restore. I can't believe that there isn't a more efficient way to do this. We are an ISP and all mail/ftp/http is served off of the netapp, any downtime will be painfull so we'd like to minimize it as best we can.
What choices to migrate the data do we have? We've considered tar/cpio over nfs but that's going to take some time even if we migrate one service at a time. dump/restore seems clumsy. and plain ole 'cp' would take forever. Apparently there are issues with volcopy going from SCSI to FCAL, is that true?
