How to securely transfer your FRITZ!Box data from the 7590 AX to the 7690: Backup/Restore, Assistant, Telephony, Mesh & VPN – explained concisely.
FRITZ!Box Data Transfer: 7590 AX to 7690 – how to migrate safely
From my tests, the switch works in 10–20 minutes if FRITZ!OS is current and the backup password is at hand.
Prerequisites and Migration Overview
First update FRITZ!OS on both boxes (7590 AX and 7690). An identical or newer version on the target box reduces queries and incompatibilities. I check this under System > Update.
Keep admin passwords, internet access data and SIP/VoIP credentials ready. Some providers require renewed confirmation on new devices.
Both devices should be powered by electricity; the 7690 preferably connected to the PC via LAN. The user interface is accessible as usual via fritz.box.
Which Data is Transferred?
The backup typically includes: Internet, WLAN (SSID/Key), Telephony/DECT, Call Lists, Contacts. Additionally, Smart Home profiles, Parental Controls, Port Forwarding as well as VPN/WireGuard and DynDNS can be transferred. Depending on FRITZ!OS, a renewed confirmation of certificates or provider data may be necessary.
Method 1: Use Backup File (Backup/Restore)
- 7590 AX: Under System > Backup > Backup create a backup file and assign a backup password.
- 7690: Under System > Backup > Restore select the file.
- Check the areas to be transferred (e.g. Telephony, Smart Home, WLAN) and start restoration.
Note from practice: With providers that have VoIP binding to the end device, the 7690 may require a new registration.
Comparison: Backup vs. Assistant
| Property | Method 1 (Backup) | Method 2 (Assistant) |
|---|---|---|
| Effort | ⭐⭐⭐⭐ – very fast | ⭐⭐⭐ – fast |
| Prerequisite | Backup file + password | Both boxes in the same network |
| Error resistance | Very robust | Robust, network dependent |
| Detail control | Finely selectable | Guided selection |

- On the 7690 start the Settings Transfer Assistant. Both boxes must be in the same network.
- Enter the admin password of the 7590 AX, select areas to be transferred.
- Start transfer and wait for the restart of the 7690.
Check Provider and Telephony Details
After migration, I always check: Internet access data and VoIP accounts are active, DECT handsets are registered, numbers ring correctly. Test call distribution, dialing rules, answering machine and possibly fax function.
Post-processing and Function Tests
- Internet stable? WLAN SSID and channel correct? Guest access reachable?
- Activate Mesh and re-pair repeaters/powerline.
- Test VPN/WireGuard, DynDNS and port forwarding – especially external accessibility.
Tip: Document your final settings and create a new 7690 backup immediately for emergencies.
Troubleshooting and Security
- Error with backup password or incompatibility notices? Synchronize FRITZ!OS version, export again.
- If necessary: Factory reset of the 7690 and repeat the transfer.
- Reset old 7590 AX (factory settings) and securely delete sensitive data.
- Fast complete migration including telephony and WLAN
- Good control over transferred areas
- Robust procedures with clear feedback
- Some providers require renewed VoIP activation
- Mesh clients sometimes need to be re-paired
- No restore without backup password
My Recommendation
For most setups, Method 1 (Backup) is fastest. Check telephony and VPN specifically afterwards. Those still undecided will find practical impressions in the test report: [url="https://www.siio.de/quack/4795/die-fritzbox-7690-im-test-besser-als-die-7590ax/",name="To the 7690 Practical Test",title="This link leads to link.de"].

Brief Summary & Recommendation: Backup settings, restore on the 7690, check telephony and mesh – done.
