How to Migrate from a Drobo or DroboPro to a Modern Synology NAS
Drobo and DroboPro systems made expandable network storage approachable by abstracting disk management through BeyondRAID. That convenience helped many home users, photographers, and small businesses build storage without learning traditional RAID layouts. However, aging hardware, limited software support, and declining drive compatibility make migration increasingly important.
Moving to a Synology NAS is less like replacing one disk enclosure with another and more like transferring a complete storage environment. Files, user accounts, shared folders, permissions, media libraries, backup jobs, and remote-access settings all need separate attention. A careful plan reduces downtime and protects the original data throughout the changeover.
The safest method is usually a file-level migration over Ethernet. Drobo disks should not be inserted directly into a Synology NAS and expected to appear as a usable volume. BeyondRAID metadata and Synology storage pools use different systems, so the source should remain intact while data is copied to a newly created Synology volume.
Assess the Drobo before buying the replacement
Begin by documenting the current Drobo or DroboPro setup. Record the model, firmware version, disk sizes, usable capacity, connection method, shared folders, user accounts, and applications that depend on the device. A Drobo may be connected through USB, FireWire, or iSCSI, while a DroboFS or similar network model may expose files through SMB or another network protocol.
Check the actual amount of data rather than relying on the advertised disk capacity. Include hidden folders, project archives, virtual machine images, and application data. Leave room on the Synology for snapshots, package data, temporary files, and future growth. A destination volume filled to 90 percent on the first day will quickly become difficult to manage.
Before copying anything, run the Drobo dashboard diagnostics and review drive health. If the system reports a failed disk, degraded protection, unusual noise, or repeated disconnections, prioritize a temporary backup of irreplaceable files. A failing source can turn a routine NAS migration into a recovery project.
Select a Synology storage design
Choose the Synology model according to workload rather than simply matching the Drobo’s bay count. A two-bay NAS may suit documents, photos, and workstation backups, while a four- or six-bay model gives better expansion options for surveillance recordings, a Plex or Jellyfin media server, business shares, and several backup targets. CPU performance and memory matter when running databases, containers, indexing, or multiple users.
For most new installations, Synology Hybrid RAID, or SHR, provides a flexible replacement for the Drobo’s expandable approach. SHR can combine drives of different sizes more efficiently than conventional RAID 5 or RAID 6, although the array still requires compatible disks and adequate redundancy. Users with identical drives and strict enterprise standards may prefer RAID 1, RAID 5, RAID 6, or RAID 10.
The file system deserves equal consideration. Btrfs supports snapshots, data integrity features, and efficient versioning on compatible Synology models. Ext4 remains reliable and widely supported, but it does not provide the same snapshot capabilities. Storage needs, supported features, and the importance of fast recovery should guide the choice.
| Area | Drobo or DroboPro | Modern Synology NAS |
|---|---|---|
| Disk management | BeyondRAID abstraction | SHR or conventional RAID |
| File access | USB, FireWire, iSCSI, or SMB depending on model | SMB, NFS, AFP legacy support, WebDAV, and sync tools |
| Data protection | Drive redundancy and Drobo protection | RAID or SHR plus snapshots and backup software |
| Expansion | Dependent on Drobo model and disk behavior | Drive replacement, storage pools, and supported expansion units |
| Applications | Limited and model-dependent | Synology packages, containers, media servers, and surveillance tools |
| Migration method | Source remains in its original format | Copy files into a newly created volume |
Readers comparing storage platforms, backup strategies, and NAS hardware can use WhichNAS storage guides as a broader reference before finalizing a model. The key point is to buy sufficient bays, memory, networking, and usable capacity for the next several years rather than recreating the limits of an older enclosure.
Prepare the source and destination
Create the Synology storage pool and volume before moving production data. Install the latest supported DSM release, set a strong administrator account, enable automatic security updates where appropriate, and configure time synchronization. Create shared folders with clear names that reflect their purpose, such as Documents, Photos, Projects, and Media.
If the Synology uses Btrfs, enable scheduled snapshots for important shared folders after confirming the available storage overhead. Snapshots are useful for accidental deletion and ransomware recovery, but they are not a substitute for an independent backup. A snapshot stored on the same NAS can disappear with the volume if the unit suffers serious hardware or filesystem damage.
Prepare the network for a sustained transfer. Wired Gigabit Ethernet can copy large datasets far faster and more reliably than Wi-Fi, while 2.5GbE or 10GbE can shorten the migration when both systems and switches support it. Disable sleep settings that interrupt the source, and avoid copying during periods when users are actively changing large files.
Copy files with verification
For a small library, copying through a workstation is straightforward: mount the Drobo share, open the Synology SMB share, and transfer data in batches. A direct computer-mediated copy is slower because the workstation reads and writes every file, but it gives users a familiar way to inspect folders during the process.
For larger datasets, use a network copy tool that can resume interrupted transfers. Synology’s File Station, Shared Folder Sync, rsync, or a computer-based utility can serve this purpose depending on the source protocol and operating system. Rsync is especially useful for repeated passes because it can transfer only changed files after the initial copy. Preserve timestamps, filenames, and permissions where the source and destination systems support equivalent attributes.
Do not erase the Drobo after the first successful copy. Run a second pass after users stop editing files, then compare folder sizes, file counts, and representative checksums. Open documents, photographs, videos, archives, and project files from the Synology. Large collections often contain unreadable files that ordinary copy operations may skip or report only briefly.
Permissions require deliberate handling. Drobo user accounts may not map cleanly to Synology accounts, and Windows ACLs can behave differently after a share is recreated. Build Synology users and groups before the final transfer, assign access at the shared-folder level, and test with ordinary user accounts. Avoid giving every household member or employee administrator access merely to simplify the migration.
Recreate services and backup jobs
A NAS migration also affects applications that point to fixed paths or network names. Update mapped drives, macOS Finder connections, media server libraries, photo applications, backup clients, virtual machines, and scripts. Keeping the old hostname temporarily can reduce disruption, but confirm that the new IP address is reserved in the router and that DNS or local name resolution points to the Synology.
Media collections may need re-indexing after the transfer. Plex, Jellyfin, Synology Photos, and similar applications should be directed to the new shared-folder paths, with attention to ownership and read permissions. Database-backed applications and virtual machines deserve special treatment: stop them cleanly, copy their data consistently, and test them before removing the source.
Rebuild the backup strategy rather than assuming RAID provides enough protection. Hyper Backup can send versions to an external USB disk, another NAS, or a supported cloud destination. Workstations can use Synology Drive, Active Backup, or their existing backup software. Configure at least one copy that is disconnected or geographically separate, and schedule a restore test so the backup is proven usable.
Validate the new NAS before retirement
Keep the Drobo online in read-only or limited-access form while the Synology operates as the primary system. During this period, monitor storage pool health, disk temperatures, SMART reports, snapshot schedules, backup results, and network performance. Review DSM notifications so warnings reach an email address or mobile device instead of remaining unnoticed on the dashboard.
Test the tasks that matter in daily use. Log in as each type of user, create and delete a test file, restore an earlier snapshot, stream a sample video, run a workstation backup, and recover a file from the external backup. If remote access is required, use a VPN or carefully configured secure service rather than exposing administrative interfaces directly to the internet.
Once the Synology has operated reliably and an independent backup is current, label and store the Drobo and its disks for a defined retention period. Do not sell or recycle drives containing personal or business data without securely erasing them. If the old unit is unusable, document the disk arrangement and preserve any recovery information before disposal.
Migration priorities for a safer transfer
Use these priorities to keep the project controlled:
- Treat the Drobo as a source device, not as a disk set that can be imported into Synology.
- Purchase enough usable capacity for current data, snapshots, applications, and several years of growth.
- Complete an independent backup before making structural changes or deleting source files.
- Perform at least two copy passes and verify important files by opening them or comparing checksums.
- Test user access, applications, backups, and file restoration before decommissioning the old NAS.
A successful move leaves the original data untouched until the new system has passed practical tests. Afterward, the Synology can provide stronger monitoring, modern backup software, snapshots, flexible RAID options, and a clearer path for future expansion.
Start by inventorying the Drobo, securing a verified backup, and selecting a Synology model with appropriate bays and capacity. Then build the new volume, copy data in controlled stages, validate every critical service, and retain the old system until recovery procedures work from the Synology and its independent backup.
