Migrate (Online RAID Leve l Migration)
During the initial setup of the TS-509 Pro, you bought a 1TB hard drive and configured it as single disk.
The TS-509 Pro is used as a file server for data sharing among the departments.
After a half year, more and more important data are saved on the TS-509 Pro. There is a rising
concern for hard drive damage and data loss. Therefore, you planned to upgrade the disk configuration
to RAID 5.
You can install one hard drive for setting up the TS-509 Pro and upgrade the RAID level of the NAS with
online RAID level migration in the future. The migration process can be done without turning off the
NAS. All the data will be retained.
You can do the following with online RAID level migration:
Migrate the system from single disk to RAID 1, RAID 5, RAID 6 or RAID 10
Migrate the system from RAID 1 to RAID 5, RAID 6 or RAID 10
Migrate the system from RAID 5 with 3 hard drives to RAID 6
You need to:
Prepare a hard drive of the same or larger capacity as an existing drive in the RAID configuration.
Execute RAID level migration (migrate the system from single disk mode to RAID 5 with 4 hard
drives).
