Migrate (Online RAID Le ve l Migration)
During the initial setup of TS-509 Pro, you bought a 1TB HDD and configured it as single disk. 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 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.
Using online RAID level migration, you can install one HDD for setting up TS-509 Pro and upgrade
the RAID level in the future. The migration process can be done without turning off the server. All
the data will be retained.
You can do the following with online RAID level migration:
Migrate the systeom from single disk to RAID 1, RAID 5, or RAID 6
Migrate the system from RAID 1 to RAID 5 or RAID 6
Migrate the system from RAID 5 with 3 HDD to RAID 6
You need to:
Prepare the HDD 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 HDD).
