Fritz!Box Data Transfer: From 7590 (DSL) to 5590 (Fiber) – Quick Step-by-Step Guide

I have tested the FRITZ!Box data transfer from a 7590 (DSL) to the 5590 Fiber multiple times. With a clean backup, the switch works in under 30 minutes – including WLAN, MyFRITZ! and port forwarding. Here is my compact but complete approach.

Overview: What gets transferred, what doesn't

The backup file reliably takes over most configurations. This saves manual clicking and avoids errors.

• Transferred: WLAN (SSID/password), telephony (phone numbers, assignments), MyFRITZ!, port forwarding, VPN.
• Need re-pairing: DECT handsets, some smart home devices (especially older models), due to wireless pairing.
• Differences: DSL vs. fiber (VLAN, authentication, ONT/SFP) – keep access data ready.

Preparation: Checklist and safeguards

• Provider documentation (fiber info, VLAN ID, access data if needed), ONT or suitable SFP module ready.
• Update both boxes to current FRITZ!OS.
• Protect backup file (.export) with strong password and store externally.

From my tests: A separate export of phone books is the best insurance against headaches with contacts.

Step 1: Create backup on the 7590

1. In the 7590: Go to System > Backup > Save, set a backup password, save .export.
2. Optional: Export phone books separately.
3. For control, note down WLAN SSID and password.

Step 2: Connect 5590 and basic setup

1. Connect fiber: Insert SFP module or connect ONT via LAN to the 5590.
2. Run through initial setup, update FRITZ!OS.
3. Set region/timezone and assign a strong admin password.

Step 3: Import settings

1. In the 5590: System > Backup > Restore and select the .export from the 7590.
2. Keep WLAN name/password – devices will then switch automatically.
3. Check/reactivate MyFRITZ! and VPN.

Step 4: Finalize telephony, DECT and smart home

• Register VoIP phone numbers, check assignments to phones.
• Re-register DECT handsets on the 5590, re-pair smart home devices if necessary.
• Test answering machine/fax (recording, forwarding).

Step 5: Fiber and network fine-tuning

• Provider specifications: Check VLAN ID, DHCP/PPPoE, GPON/AON.
• Integrate mesh repeaters, set mesh master to the 5590.
• Verify port forwarding, DynDNS/IPv6, NAS/USB.

Comparison: 7590 (DSL) vs. 5590 (Fiber)

If you're still deciding between 5530 and 5590, it's worth looking at the detailed comparison: [url="https://www.siio.de/quack/4582/fritzbox-5530-vs-5590-im-vergleich—lohnt-das-upgrade/",name="Comparison 5530 vs. 5590",title="This link leads to link.de"]

Troubleshooting and validation

• Tests: Internet speed, telephony incoming/outgoing, WLAN roaming, remote access.
• If problems occur: Check access data/VLAN/ONT, restart/reset the 5590, use diagnostics.
• Fallback: Restore 7590 with the backup if the activation date is delayed.

• help

  Will my WLAN devices stay connected?

  Yes, if SSID and password remain identical to the 7590, clients will automatically switch to the 5590.

Recommendation and next steps

Done? Then monitor the 5590 for a few days and keep an eye on logs/diagnostics. For purchase and upgrade decisions, I also recommend the direct model comparison and suitable accessories.
