Migrating a Synology NAS to a UniFi UNAS Pro 8 with Robocopy, SMB Multichannel
TL;DR
Migrating from a Synology NAS to a UniFi UNAS Pro 8 revealed unexpected performance issues, particularly with Robocopy's restartable mode, which slowed down the transfer significantly.
✦ Why It Matters
Evaluate your file transfer tools and settings to avoid performance pitfalls during migrations.
Key Takeaways
- Use Robocopy with /COPY:DATX to skip Alternate Data Streams.
- Avoid using /Z for local network migrations to improve speed.
- Experiment with /MT to find the optimal number of threads for your workload.
- Verify file integrity post-migration using Get-FileHash.
How It Works
Robocopy's /COPY:DATX flag allows users to copy file data while skipping Alternate Data Streams, which can cause errors during transfers. This optimization is crucial for ensuring smooth migrations, especially when dealing with files that may have additional metadata.
