Upgrade Configuration profile interfaces to Linode interfaces

Use this procedure to automatically upgrade all configuration profile interfaces belonging to a specific Linode to Linode interfaces.

After the upgrade:

• New Linode interfaces are created to match the existing configuration profile interfaces.
• The Linode will only use Linode interfaces and cannot revert to configuration profile interfaces.
• Private IPv4 addresses are not supported on public Linode interfaces—services relying on a private IPv4 will no longer function.
• All firewalls are removed from the Linode. Any previously attached firewalls are reassigned to the new public and VPC interfaces. Default firewalls are not applied if none were originally attached.
• Public interfaces retain the Linode’s existing MAC address and SLAAC IPv6 address.
• Configuration profile interfaces are removed from the Configurations tab. The new Linode interfaces will appear in the Network tab.
• Network Helper will now automatically exclude any shared IPs from your system’s network configuration files.

❗️

This action is irreversible

You can upgrade a Linode that uses a legacy configuration profile interface to use a Linode interface. However, this action is irreversible—once upgraded, configuration profile interfaces can no longer be used. Additionally, Linode interfaces do not support private IPv4 addresses. As a result, Linodes using Linode interfaces cannot be used with products that require private IPs.

Before you begin

If you currently have shared IPs configured and using Network Helper to automatically add them to your local network configuration files, upgrading to Linode interfaces will change this behavior. After the upgrade, Network Helper will automatically exclude shared IPs to prevent routing issues prior to BGP announcement. You must plan to configure these shared IPs manually post-upgrade or use a tool to handle BGP announcements.

Perform the upgrade

1. Log in to Cloud Manager.
2. Click the Linodes link in the sidebar and select a Linode from the list.
3. Power off the Linode.
4. Click the Upgrade button.
5. Click Perform Dry Run to verify and resolve potential conflicts before the upgrade.
   • If there are any issues, follow the on-screen instructions to fix them.
   • If there aren't any issues, move on to the next step.
