Sorry to reopen this thread, but you guys seem to have a lot of experience upgrading these systems and I want to make use of that knowledge.
I have a TS5400R that came with 2TB drives, it is FULL and I want to upgrade. This unit is being used as an ArcServe backup storage location and is configured in RAID 5 (YEA I KNOW.....) but since it is just backup storage I am comfortable with 5 since it gives me the most amount of storage with some redundancy.
I would like to keep the current backups and have them available on the new array, is it possible to replace the drives one at a time and then expand the array after all have been upgraded to 8TB drives? Or would it just make more sense to pull the current drives place in storage and reinstall if I ever needed to get something off them?
