How to move files from an old NAS to new. Snapshot replication?

Synology
1

Hello to the community,

I am currently seeking advice on how to move files from an old Synology 214+ that has a 2x4TB mirrored ext4 to a new Synology 225+ that has a 2x6TB mirrored btrfs.

I have also available an external usb drive that is used to hyper backup the most valuable things (not all) of the old nas.

My main goal is:

a)migrate the data from the old to new one, and use the new as primary

b)move the old nas to a different site (building), on the same network and act as an failover-ready-to-use backup

c)ransomware protection

I’ve read about snapshot replication with 2 options like failover or switchover but is it mandatory for the both NAS to have btrfs filesystem? 214+ does not support btrfs.

The actual data is ~1.9TB .

Whats the best way to achive all that without moving data back and forth (with least downtime)?

Simplest path to move shared folder content to the new machine is is to use Shared Folder Sync.

thanks for the fast reply!

My main question is if Snapshot replication needs btrfs to the destination NAS??

Both the client and target machines must be btrfs-formatted.

Is there another way/strategy for the old NAS to be a failover-ready-to-use backup and have ransomware protection to the new one that has btrfs??

I have also available an external usb drive, the same capacity as the old nas
