If you’re looking to migrate your Synology NAS (running DSM 7.2) to new hardware without losing your data or configuration, the best approach is to follow Synology’s official migration paths. There are three primary methods available: using the Migration Assistant, performing a Hyper Backup restore, or the direct HDD migration method. Each method suits different scenarios; here is a detailed breakdown of the workflows and what you need to keep in mind.
1. Migration Assistant
Best for:
- When both your old and new NAS models are compatible and the storage pool on the new unit is equal to or larger than the original.
- Users who need to migrate system settings, data, and packages while keeping the source NAS online during the process.
Workflow:
- Install and launch the Migration Assistant package on the destination (new) NAS.
- Follow the wizard, ensuring that the target storage pool capacity meets or exceeds the source.
- Select your source NAS and follow the prompts. The data and settings will automatically transfer to the new unit.
Pros:
- One-click migration of settings, data, and packages with minimal service disruption.
- Officially supported and straightforward to use.
2. Hyper Backup & Restore
Best for:
- When moving between incompatible hardware or when direct disk migration isn’t an option.
- Users who want to change file systems or need more granular control over what gets migrated.
Workflow:
- On the source NAS, open Hyper Backup and create a “Data backup task” to back up your necessary data and packages.
- Go to “Control Panel > Update & Restore > Configuration Backup” to export your system config files.
- On the new NAS, install Hyper Backup and select the “Restore” function to import your data.
- Restore your configuration files to finish the system setup.
Pros:
- Flexible selection of data and settings; very versatile.
- Not limited by hardware model compatibility; perfect for heterogeneous migration.
3. HDD Migration
Best for:
- When the source and destination NAS hardware platforms are compatible (e.g., within the same product family or specific Plus/XS series).
- When you want the fastest, most straightforward way to move everything over.
Workflow:
- Shut down both NAS units. Note the drive order, then remove the drives from the old unit and insert them into the new one (the order must remain identical).
- Power on the new NAS and visit find.synology.com; the status should show as “Migratable.”
- Follow the prompts to install DSM, selecting “Keep my data.” The system will automatically detect your existing volumes and settings.
- If you see a warning that “All data will be erased,” stop and double-check your drive order before proceeding.
Pros:
- Seamless transfer of all data, system files, and packages; it’s the fastest method.
- No requirement for external storage or secondary backup space.
Important Notes:
- Not all models support direct HDD migration; check the official compatibility list.
- If you are upgrading to larger drives, remember to expand the storage pool in the Storage Manager after the migration.
Migration Method Comparison
| Method | Scenario | Content | Lossless | Requirements | Notes |
|---|---|---|---|---|---|
| Migration Assistant | Compatible models | Everything | Yes | New NAS capacity ≥ old | Recommended by Synology |
| Hyper Backup | Any model/Cross-gen | Selective | Yes | None specific | Requires backup/restore |
| HDD Migration | Same series/Compatible | Everything | Yes | Hardware support required | Drive order is crucial |
Summary and Recommendations
- We recommend the Migration Assistant or Hyper Backup as the primary options; they are safer and offer higher compatibility.
- Direct HDD Migration is ideal for users confident in their hardware compatibility. Always back up your critical data before starting, just in case.
- Before you start, ensure both your source and destination NAS are on the latest DSM version, and perform a full backup of your data and configuration to prevent accidental data loss.
