ControlUp has deprecated the old Device Registration Codes across all tenants, requiring a transition to new codes for agent deployment. While new agent installations using the latest Device Registration Code proceed without issues, existing devices that were registered prior to the code expiration retain the old registration code in the Windows registry. This persistence causes a problem when these devices become inactive and are removed from ControlUp. Upon attempting to re-register, the ControlUp Agent reads the outdated, expired Device Registration Code from the registry, which leads to a registration failure. The recommended approach to resolve this for existing devices differs from the process for new installations. The latest Agent Manager deployment automatically uses the new Device Registration Code for fresh agent installs; however, it does not automatically update the registration code already stored in the registry of existing agents. Therefore, device re-registration fails if the persisted old code is expired. There is no official migration tool provided by ControlUp to update this registry value across existing installations en masse. The key registry path involved is `HKLM\SOFTWARE\Avacee\SIP` and the relevant value is `DeviceRegistrationCode`. For an immediate workaround, ControlUp acknowledges that updating the registry manually or via script on affected devices is effective. This involves stopping the SIP Agent service, updating the `DeviceRegistrationCode` registry value to the current valid code, and restarting the service. Given that agent version auto-updates are managed separately (either by ControlUp version control or via user-managed software deployment like SCCM or Intune), it is the administrator’s responsibility to ensure deployment tools push such remediation scripts or silent Agent Manager reinstalls outfitted with the new Device Registration Code to devices at scale. In practice, many organizations use deployment platforms such as Intune or SCCM to run remediation scripts that overwrite the expired registration code in the registry of existing agent installations, thereby preventing registration failure without full reinstallation. This approach balances efficiency and scale, allowing smooth transition without requiring large-scale agent removal and fresh installation. Administrators should plan to deploy these registry updates proactively to avoid disruptions caused by automatic agent attempts to re-register post device inactivity cleanup.
