| Q: I run four 400GB SATA drives configured with RAID 5. I want to replace them with four 750GB drives. Can I rebuild and then swap individual drives?
The usual way to migrate data with internal server-based storage is to copy the data to a separate set of drives or temporary storage, install the new drives and then copy everything back, remembering to preserve all file attributes. A tool like Robocopy can do this.
