This article shows you how to transfer a DDNS hostname to a different Synology device (e.g., NAS, NVR, and Router) by using either the same or different Synology Account.

Using the same Synology Account

If you need to access your old Synology device after transferring your DDNS, make sure you have another external connection method available, such as QuickConnect. After transferring, your DDNS will no longer be used to access your old Synology device.

1. On the new device, sign in to the same Synology Account that you used on the previous device.
   • DSM 7.0 and above: Control Panel > Synology Account
   • DSM 6.2 and below: Control Panel > Info Center > Synology Account
   • SRM: Control Panel > System > Synology Account
2. Enter the previous DDNS hostname on the new device at the following locations:
   • DSM 7.0 and above: Control Panel > External Access > DDNS > Add
   • DSM 6.2 and below: Control Panel > External Access > DDNS > Add
   • SRM: Network Center > Internet > QuickConnect & DDNS
3. Click OK and then click Yes in the pop-up window.

Using a different Synology Account

1. Sign in to the Synology Account you used on your original Synology device.
2. Go to Devices and select the original Synology device.
3. Go to External access > Synology DDNS > Action > Unlink.
   
4. Click OK in the pop-up window to unlink your DDNS from the device.
   
5. After 24 hours, configure the same DDNS hostname on another Synology product.
