Why each option
To avoid a license error when restoring a UCS archive to an RMA replacement BIG-IP device, the administrator must use the `tmsh load sys ucs` command with the `no-license` option.
The `tmsh load sys ucs <filename> no-license` command instructs the BIG-IP system to restore the UCS archive without attempting to restore the license information. This is crucial when moving a UCS between different hardware devices (like an RMA replacement) because license files are tied to specific hardware IDs and will not be valid on the new device, causing the restore to fail.
Revoking the license is typically done before decommissioning a device and does not resolve the issue of restoring an old license to a new hardware unit.
Reactivating the license on the new device is a separate step needed to get the new device fully licensed, but it does not prevent the failure of restoring a UCS archive that contains the old, hardware-tied license.
Manually removing license information from a UCS archive is not a supported or practical method and could potentially corrupt the archive; the `no-license` option is the designated solution.
