Low level user, guide my upgrade please

Hello all. I have a DS420j with SHR and 4 4TB HDD. Used for mainly storing photography and music production, PLEX server and Time machine backups. I want to use it more and I would if it performed better (faster) hence the upgrade.

I have a new DS423+ coming tomorrow with 2 16TB HDD, 4GB RAM, and an NVMe SDD.

My plan is to pop in the SSD and RAM and setup the new NAS with SHR-2 and the 2 16TB drives as a new setup. Which filetype is recommended for my use? BTRFS?

Then I believe I would setup migration assistant on new NAS and copy all files on old NAS over to new one.

Then I’d like to add 2 of the 4TB drives to the new setup and sell off the old one with 2 4TB drives. How do I wipe the old machine and HDD’s?

Can ya tell me if I’m on the right track here? Any more specific advice/process is welcomed.

Thanks

Yea… don’t do that. SHR is the correct response.

That would be a new pool. You cannot add smaller drives to an existing pool/volume.

The machine wiithout drives does not need wiping. For the drives themselves… connect to a Win PC and Google “diskpart clean all”.

SHR, got it.

So I can add the drives but will be a new pool. Pros/cons? Uses for having multiple pools?

Thanks again

Looking deeper into this it appears as though I may NOT be able to set up new NAS with BTRFS and migrate the old EXT4 volume? is this right?

For my needs will EXT4 be good enough?

If you are satisfied now, it will probably be good enough. However, btrfs offers protection against bitrot, which can go undetecded in photos and music. Additionally, several advanced packages (ex., Snapshot Replication) are available only with btrfs-formatted systems.

Presuming you have maintained full backups of your content and packahges (using Hyper Backup), you would restore to a new SHR (btrfs-formatted) volume on the new NAS (16+16+4+4).

But realistically, I’d drop adding the 4 TB drives, and wait until you need that 3rd 16 TB. That way, your 4x4 TB set is preserved until you are certain everything is fine on the new unit.

Sounds good. I think I’ll do as you suggest and go with 2x16TB on new machine, Migration Assistant keeping ext4.

I’ve installed SSD, RAM, HDD, Storage Pool but when I went to migrate I hit a snag.

So apparently my DS420j is not compatible for using Migration Assistant

All I’ve seen was that Source NAS was on proper DSM version.

Next method?

The next best way is to restore from a Hyper Backup backup.

For the new NAS, you would create an SHR volume (btrfs formatted); install Hyper Backup; link to the backup you created from the 420j; and restore your content to the new machine.

Thank you. I have this in progress now. It is making the backup at 40 MB/s and I have about 9TB. This gonna be a while but imagine its normal?

So it took a while to backup now I’m restoring that backup from the new volume onto the new volume and am at risk of running out of disk space!!

will have about 400GB to spare when it finishes in 7 hours or so!!!

So I will delete the backup and recover the 7.4 TB or so of storage??

Will this work out or did I do something wrong?

Thanks
