Switching Fibre Providers: The Hassle-Free Migration Guide
Executive Summary
If you're unhappy with your current ISP's speed, support, or pricing, you don't have to stay. In 2025, switching fibre providers (known as "migration") is a standardized process. However, if done incorrectly, you could end up with a week of downtime or a surprise bill from your old provider. This guide provides a step-by-step roadmap to a smooth transition.
The Migration Process
Unlike a new installation, a migration doesn't require new cables or a technician visit. It's a "logical" switch that happens in the software of the FNO.
Step 1: Check Your Current Contract
Ensure you are outside of your "clawback" period. If you've been with your ISP for more than 12 months, you are usually free to go.
Step 2: Give Notice
Most ISPs require a 30-day notice period. You usually have to do this via their online portal or a formal email. Do not cancel your line yet; just give notice.
Step 3: Get Your Migration Key (if needed)
On some networks (like Openserve), you need a "Migration Key" or "B-Number" from your current ISP to give to your new one.
Step 4: Order with the New ISP
Sign up with your new provider and select the "Migration" option. Tell them your desired "Switchover Date" (usually the 1st of the next month).
Step 5: The Switchover
On the morning of the switchover, your old router will stop working. You simply plug in the new router (or update the settings on your old one), and you're back online.
Comparison: Migration vs. New Install
| Feature | New Installation | Migration (Switching) |
|---|---|---|
| Technician Visit | Yes | No |
| Lead Time | 3 - 15 Days | 1 - 30 Days (Notice period) |
| Downtime | None (New line) | 1 - 4 Hours |
| Setup Cost | R1,500 - R2,500 | R0 - R500 |
Common Pitfalls to Avoid
- Double Billing: If you don't give proper notice, you might end up paying both ISPs for one month.
- The "Release" Issue: Sometimes an old ISP "holds" the line on the FNO's system, preventing the new one from taking over.
- Router Compatibility: Ensure your old router isn't "locked" to your old ISP if you plan on keeping it.
Practical Checklist: The Smooth Switch
- Confirm your Notice Period: Is it 30 days or a full calendar month?
- Request your Migration Key: Do this at the same time you give notice.
- Order New Service Early: Don't wait until the last day of the month to sign up with the new ISP.
- Backup your Settings: If you have custom Wi-Fi names or port forwards, write them down.

Frequently Asked Questions
Will I lose internet during the switch?
If coordinated correctly, the downtime is usually less than an hour. The old service is deactivated and the new one is activated almost simultaneously.
Can I switch FNOs (e.g., from Vuma to Openserve)?
No. That's not a migration; that's a new installation. You can only 'migrate' between ISPs on the same physical cable.
Is there a fee to switch?
Most new ISPs will handle the migration for free to get your business, but your old ISP might charge a small 'admin fee' for the release.
