4. NAS Migration
You can migrate data and settings from your current NAS to another NAS model with minimal disruptions
by installing all the hard drives from the source NAS to the destination NAS. RAID configuration and other
settings are retained on the destination NAS after migration.
NAS migration requirements
You can only migrate drives to specific NAS models, depending on your source NAS. For the list of NAS
models compatible with direct NAS migration, see
https://www.qnap.com/go/nas-migration
.
Your device must meet the following requirements:
• QTS NAS supports several types of NAS migration:
• ARM NAS to an ARM NAS
• x86 NAS to an x86 NAS
• ARM NAS to an x86 NAS
Note
You cannot migrate from an x86 NAS to an ARM NAS.
• The destination NAS must run on the same QTS version as the source NAS (or later).
Important
Due to incompatibilities in file system, system migration between QTS NAS and QuTS hero NAS
is not supported.
Warning
Migrating drives between QTS NAS and QuTS hero NAS can cause data corruption.
• The destination NAS must have sufficient free drive bays to accommodate all the drives that you are
migrating from the source NAS.
For NAS models that do not support NAS migration, you can migrate existing data using HBS 3. For details,

keys of encrypted disk volumes in a safe place. You can
also choose to decrypt disk volumes before migration.
