Currently using Synology 1821+ with all bays filled with ironwolf pro 8TB drives. Was gifted an Synology 923+ for Christmas which I would like to use as main NAS and the 1821+ as backup NAS. I have purchased 12x 12TB irowoolf pro drives to updated both boxes. Can you assist me in the best way to get the current data located on my 1821+ to the new drives in the setup I am planning. Do I make a backup of all the data and just restore data onto the boxes after I have set them up? Is there a way to migrate my data in a easy way
There are a few options to move your data from the Synology 1821+ to the new Synology 923+ setup:
Backup and restore: You can create a backup of your data on the 1821+ using the built-in "Hyper Backup" or "Sync" feature, then restore it onto the 923+ after setting up the new drives.
Data migration: You can use the "Migration Assistant" in the Synology DSM to easily move your data and configurations from the 1821+ to the 923+. You can connect the two NAS devices via a network cable and follow the instructions in the Migration Assistant wizard.
Direct copy: You can also directly copy the data from the 1821+ to the 923+ using a file explorer, such as Windows File Explorer or Finder on a Mac. Connect the two NAS devices to the same network, then copy the data from the source folder to the destination folder.
If data stays on the ds1821+ you can simply replace one drive at the time and let the rebuild finish

Regardless of the method you choose, make sure to properly format the new drives before using them in your Synology NAS setup.
