Suggestions for one-time NAS to NAS file transfer?

My old TS-251 RAID 1 is dying. I never used it for anything except file storage.

Bought a new TS-264. Two new HDDs are installed and configured also as RAID 1. Step one: copy all the files from the 251 onto the 264. Suggestions?

I’ve read a lot of advice, but most of it focuses on permanent setups with two NAS devices, which I’m not doing since the old 251 is going out of service after the transfer. Or trying to install the old disks into the new NAS (nope not compatible).

Can I use the USB C ports on the front of each to automagically connect the two storage systems? Do I need to use HybridMount? Or set up both as simple networked file shares, connect to both from a PC, and copy from one to the other? Or really brute force: copy parts of the source 251 onto a PC, then copy those files over to the 264?

What do you think?

Easiest and safest - setup shares and both, copy the files. If something goes wrong, you still have the originals (and I hope you have backups elsewhere of anything important in any case). This is not the most efficient though, as it use your PC to copy, so double the transfer.

Also a good option, setup HBS3 to copy the files. This is direct NAS to NAS.

Lots of other more complex options available.

I would use Hybrid Mount and copy the files from one to the other. Set up NFS sharing on the folders you want to copy (I think NFS is faster than Samba but you have to specifically set it up). Then you can mount the old NAS folders on the new NAS and copy away.

As @dosborne suggests, HBS is also a good way to do it. Effectively, you would “back-up” the entire contents of the old NAS to the new NAS. This though would require some work to the move the folders out of the “backup” directory and put them in all their correct places as HBS has a specific folder tree it uses when backing up.

Connect the NAS’s directly with a network cable. Use HBS.
