Whether you need to change devices when migrating to IPv6 depends on several factors, including the compatibility of your current devices with IPv6.

We give you a general guide to evaluate whether you need to update or replace your equipment for migration to IPv6:

1. IPv6 Compatibility Assessment

• Network Devices: Check if your routers, switches and other network devices support IPv6. Many modern network devices already support IPv6, but this may require a firmware or software update. If your devices are relatively new, chances are they already support IPv6 or can be updated to support it.
• Servers and Operating Systems: Most modern operating systems (Windows, macOS, Linux) support IPv6. However, you will need to ensure that any specific server software or applications also support IPv6.
• End User Devices: Computers, smartphones and other end devices released in recent years generally support IPv6. You may need to revise your settings or perform software updates to enable IPv6 support if it is not enabled by default.

2. Migration Planning

• Migration Strategy: Depending on the size and complexity of your network, you can consider a direct migration to IPv6 or a dual coexistence strategy where IPv4 and IPv6 work in parallel. This may influence your decision to upgrade or replace equipment.
• Training and Preparation: Make sure your IT team is trained in IPv6, including network configuration, security, and troubleshooting.

3. Upgrades and Replacements

• Update vs. Replacement: If the devices do not support IPv6, you should consider replacing them. For those devices that can be updated with new firmware or software to support IPv6, this may be a more cost-effective option.
• Suppliers and Support: Check with your hardware and software vendors to determine IPv6 support and available upgrade options.

4. Security Considerations

• Security Updates: Ensure that all security measures, including firewalls and intrusion detection/prevention systems, are IPv6 compatible and properly configured for the new environment.

5. Testing

• Test Environment: Before a full deployment, it is advisable to set up an IPv6 test environment to identify compatibility, performance, and security issues.

In conclusion, it is not always necessary to replace all your equipment to migrate to IPv6, especially if it is relatively modern.

The key is to conduct a detailed assessment of your current infrastructure's IPv6 compatibility and plan accordingly, taking into account both software/firmware upgrades and hardware replacements when necessary.
