extend D1000 RAID 5

We have a D1000 in split array with 6 - 36 GB SCSI on a side. Would like to replace these with 6 - 146 GB Seagates (Sun derived) to increase the storage capacity. This is a RAID 5 array with slice 4 flagged 'wm' and cylinders at 0-24616. If I partition the new drive(s) in an identical fashion, but with cylinders = 0 to approx. 100000 can I replace the drives one at a time and resync - or is that too easy? Would it be better to just reconfigure the D1000 with the new drives and restore the filesystem from tape?

TIA
